Hello, my name is Honecat. I am restarting my fish collection after 15 years. The last time I had a fish tank was before the earthquake of '94. I currently have an irredecent shark, an Asian upside down cat, a male beta, and 2 blood fin tetras. I have them all in the same tank. We just lost our bumble bee cat due to severe ick. My main goal is to get a larger tank and have more of the cats and irredecent sharks. I currently have a 20 gallon tank, and any advice would be greatly appreciated. I also do plan on moving up to a bigger tank within the next few months again.
