Ideas for fish for a 20 Gal aquarium?

[macdav07]

For 10 years I've had a Hagen Waterhome 20 Gal Aquarium. I've had guppies, tetras, and mollies. Now that my last tetra has died of old age, I want to start fresh. Any ideas of what fish to get? Or should I convert my tank to a saltwater reef tank?

Can you post the dimensions of the tank and the hardness and pH of your water, please? We don't like to recommend species without knowing those

Your tank might be a bit small for a reef, and for a first time marine tank. Marine tanks do need to be kept very stable, and bigger tanks are easier to begin with. You'd need to spend a fair bit on new equipment as well; mostly lights and a protein skimmer.

You could do some of the smaller Gourami types if you'd like. Honey, Sunset, and chocolate gourami's are relatively smaller. You could do 4 Honey's or 4 Chocolate's in a 10 gal. I'd probably only do 2 Sunset's because you'll probably want a smaller pleco and maybe a cory.

My vote goes for a small group of shell dwelling cichlids.
