ok so ive recently heard that you can keep a single german blue ram in a 10 gallon tank. could i do a single with a shool of like flame tetras or about the same size schooling fish?
Probably best to focus on getting your 55g running smoothly before trying to set up another one, especially if the fish you are interested in is a species known to be sensitive and needing an established tank.
i just dont want the biological filter to die off while i wait for my plants to grow in. i think ill get a simple betta.i agree... only in a 20l... but i disagree with the point about colors being washed out without a mate. my male bolivian ram's mate passed, and his colors are great, if not better then he was with a mate. i would definitely concentrate on the 55. i know empty tanks are hard to deal with lol, but its best to concentrate on one tank at a time.
