I added some Clown Loaches to my tank for some snail control and wanted some advise as far as any issues that I might have. They were added to a tank that has been established for three years (they are the first addition to the tank in over two years). The tank footprint is 60"X 18" X 24" the substrate is sand and i have some live plants. I change 30 gal (113.56 liters) once every seven days. The temp of the tank is 79.6F (26.4C).
Water chemistry is as follows:
NH3 = 0 Mg/L
NO2 = 0 Mg/L
NO3 = 20-40 Mg/L
pH = 8.9
Total Hardness = 16 dH
The species that they are housed with are: Cyathopharynx furcifer (Ruziba) which is an omnivore and Wild Caught Cyprichromis sp. Leptosoma (Kitumba) which is a carnivore (Both of these species are not from lake Malawi). They are quite docile species of cichlids, hence the reason I did not add another species of cichlid for snail control as they would "tear" up the species I have in this tank.
I feed a mixture of sprulina and omega one marine flakes (as it contains a higher meat base than their cichlid flake) as well as frozen mysis.
here are a few pics of the tank (prior to the addition of the loaches)
