my brother is setting up a 20 gal tank and keeps bugging wanting to know what fish to keep in it. he wants quite a few fish in it even tho its only 20 gallons. what do you guys think? hes new to fish keeping keep in mind
I do agree, I had a fraternity of 3 male bolivians in my 37 gallon, and while they were peaceful and nice to look at, they weren't all that interesting. They would stick to their own areas, once in a while one would drift into the others' area and get chased out. That's it... A breeding pair would definitely be interesting to watch, but I'm sure there are other species that are more interesting... perhaps apistos or kribs
