Yes, a single Angel in that size of a tank would do well with some larger peaceful community fish. I wouldn't do Mollies, that's like keeping Bettas with Goldfish. Mollies are brackish fish, they like a little salt in their water. They can live in fresh water but they are not thriving, just surviving. You would be better with bottom dwelling fish, as Angels are Cichlids and very territorial, so a fish that's not in their space would be better. Google it though.
Tetras, Rainbow Fish, Rams, Swordtails, Danios, Rasboras, Platy, Loaches, Cory, Barbs, Kirbs are all nice fish.
Look at these....
Bolivian Rams, a Dwarf Cichlid. They go good with Angels.
Personally, I wouldn't put them in with a Betta. They are the same breed of fish, depending on the Gouramis and Bettas personality though.
While Angels and Gouramis can sometimes get along as well, they also might fight. If the behavior continues, you may have to return one of them, especially if there is a size difference between them. It is unlikely that it will work out. Doing this fish stuff by the books sucks doesn't it? lol
Alright, I was just wondering cause I really like them and I was going to show her them when she got out of bed.
Yeah, stuff by the books is almost never fun! lol!
The tank she wants is a 5 gallon, but I wanted to get her something bigger so she could have a nice community tank... I'd have to get a 20 gallon er something like that though.
Ya know.. my local pet store puts shrimp in those tanks lol Wouldn't be good for anything but a school of neon tetras or guppies sadly! Or a Betta fish but then you'd have to mod the crud out of it to make it safe. You could get a 20g set up for the price of them :)
