Welcome to Freshwater Aquarium Fish! My mission is to provide easy access to the knowledge and experience that aquarists need in order to be successful. Hopefully we can not only keep more people involved in the hobby of keeping tropical fish aquariums, but also improve the level of care that our aquatic charges receive. This site is intended not only for beginning aquarists, but also those who have been in the hobby for many years. It is my hope that this site will grow into an on-line community where hobbyists can share their triumphs and defeats; to help one another to learn and become better aquarists.

Thorichthys meeki is anything but meek. Like most cichlids, they are to be kept as a single species tank, or at least with fish of similar size and temperament. This species is usually found in the lower and middle sections of slow-moving rivers. Its natural habitat includes mud or sand-bottomed rivers and rocky ponds. T. meeki uses shoreline vegetation for protection. These fish are omnivorous, but algae makes up the main part of the diet. In a home aquarium, T. meeki should be provided with plenty of space, driftwood, rocks, and a sand or fine gravel substrate. They will eat literally anything you offer them including pelleted foods, flake foods, and fresh or frozen shrimp. Also, they will graze on aquarium plants. Breeding Firemouths is relatively easy. The difficult part is getting a male and female together since this species has no pronounced sexual dimorphism. The easiest method is to raise a group of six or eight and let them pair off naturally. Females lay from 100 to 500 eggs at a time on a flat rock. Both parents will vigirously protect the nest from other fish.

Probably the most important step in starting a new aquarium is letting the tank cycle. Cycling is the process that starts the biological filter. During the cycle, the necessary colonies of Nitrosomonas and Nitrospira each take hold and grow. The colonization of the filter and gravel by Nitrosomonas (AOB) initiates the nitrogen cycle. After this, a natural succession occurs where the AOB convert ammonia in the aquarium to nitrite. Before the next wave of bacteria, Nitrobacter and/or Nitrospira, can colonize the aquarium two conditions must be met. First, there must be sufficient nitrite in the water for these NOB to take hold. Second, since growth of these bacteria is somewhat retarded by ammonia, the ammonia concentration must be brought nearly to zero by the AOB. So there is a population dynamic where the AOB population explodes because of the large amounts of ammonia in the water. They quickly use this up and produce a nitrite spike. Since the ammonia level is low, the AOB population starts to die back. At the same time, the nitrite spike fuels an explosion of NOB. When the nitrite is used up, the NOB start to die back. All of these dying bacteria, together with whatever food is being added to the system, decomposes to ammonia, which feeds the AOB population. The pendulum swings back and forth until the AOB population just keeps up with ammonia input, and the NOB population just keeps up with nitrite production. When these cultures are in equilibrium, the ammonia and nitrite concentrations are maintained at or near zero and the tank is said to be cycled.

Think, Plan, Research!
The most important step when setting up a new aquarium is, without a doubt, the planning and research. Many aquarium fish deaths can ultimately be blamed on poor planning and research. Too many aquarists run down to the local fish store (LFS) and buy a bunch of fish that catch their eye. In a few weeks, after one fish has devoured all of its tank mates, they realize they should have learned a bit about the animals they put in their tank. A few hours of reading can avert unnecessary livestock losses.
Here are just a few questions that should know the answers to before you buy that tank:
- What kind of animals do you want to keep?

This an easy one, right? Don't you just pour in tap water? If you want rapid temperature and pH changes to stress your fish and for chlorine/chloramine to dissolve their gill membranes, then by all means use the water "fresh" from the tap. Seriously, everyone should treat their water to (1) remove the toxic chorine/ chloramines added to most municipal water supplies, and (2) match the temperature (and pH if necessary) of the existing aquarium water. It is imperitive to remove sanitizers like chlorine and chloramine from aquarium water. Many cities add these compounds to their water supplies in order to kill literally everything but the person drinking the water. Chlorine and the related chloramines do not affect humans significantly, but they are terribly toxic to microorganisms and, even worse, to your fish!
