Hi everyone! I have 6 fish in a ten gallon tank: two black skirt tetras, two serpae tetras, and two male guppies. Everyone got along for months until my black skirts doubled in size and now they are really picking on my guppies. Each has nips taken out of their tails and look stressed. I want to move my guppies to their own tank (then I can get more tetras maybe, lol). I bought a little $20 tank at the store (comes with an air pump and a light, but nothing fancy). Got home and set it up, using rocks and some water from the cycled tank. It's only one gallon, though, and seems kind of small for two guppies. Looked bigger on the box. I put a plastic plant in there and it looked cramped! What should I do? Is 1 gallon enough for two little guppies? I can take out the plant, but do guppies need plants? Also, the pump is quite loud, louder than the hang-over-the-rim filter in the 10 gallon tank. I don't even know if guppies need a pump, though I think it would probably help with oxygen. Any wisdom for me? PS: I know two male guppies is not ideal. If I can find someone with guppies, I might attempt a trade, but not sure what to get or what to do in the meantime.
