I'm trying to set up a simple 10 gallon tropical fish tank with about 3-6 fish in it and it contains artificial plants and rocks with holes for the the fish to swim through, this is to entertain my cats and myself. I don't want fry and I don't want any complications.
I was told by the fish guys at Petco that gouramis, plats, guppies, etc are not hardy enough for the cycling process and that I had to start with danios. I thought just 3 danios which are very small would be no problem starting out. They are only 2 inches, so that only takes up 6 gallons of water. I have 4 gallons of water left for a couple more fish, Danios can't live as a trio in a 10 gallon tank with 2 fish of a different species? According to the fish guys at Petco that would be fine.
If I do have to get rid of my danios, then how can I cycle the tank and produce a successful tropical 10 gallon aquarium since I don't have the space for anything larger.
I've read on this forum that female bettas can be kept together. I didn't know that. I thought even they would fight. Can I keep 5 female bettas in a 10 gallon tank without problems? If yes, perhaps that would be a solutionl.
