So one day I got home from work and I have a tank with 2 fish in it. A black moor and a comet. I am thinking they are both young because they are smaller. I instantly became attached and now they are my fish even though they were bought for my children. What worries me is that they are only in a 3.5G tank. I feel they need a bigger one. I can't wait to get more advice and learn how to take care of these little fish "Stormy and Paws"
