Aquarium Fish Information Pictures Behavior Notes Biology

Each fish also limits the growth of the other fish by secreting growth-limiting hormones (GLH) into the water, which explains why some fish grow more rapidly than others.

Unfortunately, if a tank is overcrowded, fish that grow large in the wild will become deformed, as bone growth often exceeds muscle growth when oxygen levels arent high enough. Other fish are simply crowded out and die "mysteriously." This happens frequently in saltwater aquariums that are overstocked

They can then be swiveled to finesse the dynamic of water flow in the aquarium as corals grow or wane, or when the seascape changes for any other reason. A slight restriction of water flow can be achieved by heating another short stem of pipe and crimping it to produce a restricted flare-tip that will increase the velocity of effluent water. This modified nipple is to be placed, of course, into an effluent tee. Some discretion is required here, however, as the resistance from a single crimped outlet will likely translate into water taking an easier path of resistance namely, another open outlet(s). To compens

Modern filter plates, commercial and custom-made utilize chemically inert materials to provide continuous, even flow through the whole systems base. The best incorporate large (one inch plus) air-lift, powerhead and pump driven mechanisms. (photograph).

There is nothing wrong with airstone-only driven systems. These move a goodly volume of water, with the added benefit of increased gaseous diffusion; while not adding extra waste heat. Air pumps are the "lowest-cost" provider of water movement.

Laugh if you will, you old

We change the bulbs, and the animals and algae spring back to life! That simply doesnt happen as often in the reef aquariums we maintain which use metal halide and/or Power Compact lamps. Therefore, for reef aquariums that employ VHO lamps, we recommend changing these bulbs two to three times a year in order to maintain the overall health of the environment.

The other problem we have encountered with VHO lighting is that for some

To assure this last point is clear. Having low (less than ten ppm) nitrate is desirable, but not essential with fish only, live rock and algae systems.

Your goal in preparing an environment suitable to support your animal livestock is to first get populations of these two bacteria groups going in your new aquarium.

College classes are beginning, but that doesn't mean you have to give up on pets just because you live in a dorm or small apartment. Mini-aquariums can be....

Daphnia For The Aquarium

Daphnia are a great food source for both young and adult aquarium fish, you could catch them with a net in a pond, but their's a risk of bringing in parasites. I just found an article about growing daphnia yourself, nice read for the real tinkers out there :-)
