Yes and No. This depends on the type of cichlid you're keeping. Many cichlids will move gravel to all parts of the aquarium and uncover the UGF plate, which renders the UGF useless. For this reason, UGFs are bad ideas for MOST cichlids. However, for fish like the Cyprichromis that like fairly still water and do not dig, an UGF would be a perfect filter choice. UGFs are also good for raising baby cichlids in as well.

Before they are old enough to court and breed, most cichlids will coexist peacefully with other fish of different types (although due to their playfulness and appetite, fish with long, trailing fins and fish small enough to fit in the cichlid's mouth should be avoided). Young cichlids will establish a pecking order among them, and are generally less interested in other species.

Most pet stores carry cichlids and a few specialize in rare and hard to find species. You can also buy cichlids on the internet, generally from individuals who sell them. One of the best places to buy fish is at GCCA meetings where members bring in fish to sell each month. GCCA also hosts large public auctions and swap meets. You can visit GCCA's calendar to find the next auction or swap meet.

Cichlids usually form a hierarchy of dominance in a tank, and normally only the dominant male of a given species will fully display his colors to their fullest extent. Often times, non-dominant males will seek to hide their colors and appear less threatening, or at least incur the aggression of the dominant individual less often, by sort of masquerading as a female or juvenile. This can occur with females as well, but is usually more often noted among males.

Just like humans, cichlids will promptly begin to personalize their territory once chosen. To the cichlid, there are several considerations:

A lot of people don't realize that an undergravel filter serves as a biological filter, and not as a chemical or mechanical filter. In other words, there's no physical removal of debris from the aquarium water. Sometimes too, the tank is presented with a large bio load ( lots of fish) before the filter is ready to handle it, or even while the tank is still being cycled. Take your time adding fish.

Sponge filters are great for filtering tanks containing baby fish. Not only can they easily handle the waste the baby fish produce, but sponge filters actually have many microorganisms growing on them that little fish graze upon between feedings. They also won't suck up your baby fish like a power filter will. Sponge filters are also great if you own a large number of aquariums.

attractive substrate makes the tank look nice, can trap some dirt or hide it, and provides anchor for roots of plants. Some cichlids use the gravel (spawning pits, etc.) and gravel can help to buffer the water and, in some cases, provide a substrate for nitrate cycle bacteria. The size of gravel you choose will depend on the type of cichlids you are keeping, whether you want to have a planted tank, and whether you want to breed your fish.

What kind of personality do you want in your fish? Some cichlids are quiet and sedate, others are aggressive and territorial. Cichlid behavior is fascinating to watch and we shouldn't make value judgements that aggressive fish are bad. . . they are just following nature.

In general, we recommend keeping cichlids in a species tank. Some cichlids may bully the more common non-cichlid species such as livebearers, gouramis and tetras. Some cichlids get big enough to eat them! This dwarf cichlid may be kept in a community tank and only becomes aggressive when spawning. Both males and females are attractive; females have a beautiful cherry red belly. A substrate spawner which appreciates a cave or flowerpot to spawn in.

Many cichlid species are easy to breed for the beginners Most cichlids do best in a species tank, as virtually all cichlids can get aggressive during spawning. Here are two examples of cichlids that are fairly easy to breed, but there are many others. This substrate spawning fish spawns readily and at a young age. We've seen them spawning in pet shop tanks! The traditional striped and a pink variety are available. Provide a flat piece of rock for spawning.

Some active cichlids are much happier with a lot of swimming space. Other dwarf cichlids, such as Tanganyikan shell dwellers, are perfectly happy to stay in a six-inch square territory on the bottom of the tank.

Cichlid-only community tanks-- usually with non-cichlid scavengers-- are very common in the cichlid hobby. Experienced cichlid keepers often find unlikely combinations of cichlids which work well by chance (e.g. a shortage of tank space, or a fish jumping into another tank). Aquarists will commonly attempt to group fish of similar geographical origin, e.g.

Fighting in cichlids can either signify a struggle for territory, dominance, an element of courtship, or all of the above. In many cichlids, fighting will have a theatrical, ritualistic quality, with spectacular displays of color and finnage, posturing, and lots of gill flaring Gill flaring, in particular, is an overtly aggressive gesture as it makes the head and thus the whole fish appear larger.

There are many methods that work, here is mine! Most important is quality food. I feed twice a day during the week (flake food in the morning and baby brine in the evening) and 3 times a day on weekends (one extra feeding of flakes). Never feed more than they can eat. Keep the temperature and the water quality constant. I do water changes weekly on my fry tanks. I drain about 25% of the water out and then refill with water from the adult tanks.

Many cichlids are aggressive and territorial... especially when breeding. Some grow big enough to make a quick snack of your guppies and swordtails.

It is not necessary to remove your UV filter when you're going to use any other filter you may have, but it won't do any harm. Some filters, like polarizers, do cause image degradation because of their construction. This degradation is usually more than the degradation already caused by the UV filter, so in those cases you do not really have to remove the UV filter. On the other hand, you run the risk of light being 'trapped' between the two filters, thus causing lighter spots on your picture.

That really depends on what kind of cichlids you will be keeping and the type of setup. If you are looking to set up a nice decorative tank for the family room, I would suggest either a power filter that hangs over the side of the aquarium (i.e. a Whisper power filter or a Marineland biowheel), or a canister filter (i.e. Magnum 350, or Fluval). Filters such as these can perform large amounts of filtration and keep tanks very clean.

The manufacturers will have us believe that you can block out any unwanted reflection in glass, water etc. You can not block out the reflections in metallic surfaces, since they do not polarize the light. But, although the manufacturers are right for the greater part, you will have to use the polarizer in the right way to get the above effect. This means, you will have to take your picture in a direction perpendicular to the sun (i.e.

The best way to ensure proper oiling is to use our squeeze bottle recharger kit (Part No. 99-5050). With a squeeze bottle, you simply run a bead along the top of each pleat on both sides of the filter. If using an aerosol recharger kit (Part No. 99-5000), make one light pass over the entire filter area front and back. The oil will then be evenly absorbed throughout the rest of the cotton medium over the next several minutes.

No, this can blow the filter material right out of the wire mesh and ruin the filter. Pick a nice day to clean the filter and let it dry naturally. A low pressure air flow such as from an industrial drying machine or blow dryer will help the filter dry more quickly.

Please use 0.25 as the default value for the target load. In particular, for Part II of the lab, please use 0.25. As with open addressing, you also want to allow the application to provide a value for the target load in the constructor. In Part III you are asked to perform tests with target loads of 0.25 and 0.125. You can look at the provided code for the open addressing bucket mapping to guide you. (The only difference is that for open addressing 0.5 is used as the default value, and 0.

There are two types of filter, one for bluescreen and one for greenscreen. The bluescreen filters have a red tone and the greenscreen filters, a magenta tone. This assists with the colour correction of the image. To help further, within each type of filter there are two levels of colour correction - 15CC & 25CC. The choice of which to use depends on the levels of spill and fringing and how difficult the shot will be to key - 25CC for difficult shots, 15CC for easier.

There are so many different species of New World cichlids that no one answer can provide the answer. Follow these general guidelines should work well with most cichlids that breed in pairs. Cichlids are extremely aggressive fish as an everyday temperament. Imagine them when they want to spawn! I like long tanks for breeding cichlids. The greater the distance between male and female, the better.

No. These are very poor methods of monitoring your water filter for maintenance. Once the bad tastes have returned, it is already far too late - contaminants have passed through the filter and into your drinking water. A carbon cartridge may be able to control taste and odors long after the carbon has lost its ability to effectively reduce other toxic contaminants. You should always follow the manufacturer's filter replacement schedule to ensure optimal filtration.

UV and skylight filters are useful when you are taking pictures in the mountains or at sea or any other place where there is a lot of UV light. It will filter out the blue haze that normally blurres the background of your picture. It is also very useful when taking pictures in the snow, since snow is a very good UV reflector.

Today's health conscious population is concerned about eating the right foods and the trend has been towards a high fiber diet. This fact coupled with various illnesses, produce intestinal gas discharges, commonly know as flatulence, crepitating, breaking wind, cutting the cheese, or farting.
