Can an angelfish be kept in a 20 gallon tank? And if not, are there any fish that look like angelfish that can be kept in a 20 gallon? I have only had guppies and a few plecos before, so I'm not very experienced.
Hi, good question. Angelfish need 10 gallons per fish so 20 gallons is fine. However, they can be aggressive so in a tank that size one fish may be best. If you have a breeding pair, then that is perfect for them if they are the only fish in the tank. Make sure the tank has fully cycled or the fish will be in danger. Get a test kit to know if it has cycled. If you don't know what the nitrogen cycle is please research it on this forum. We have tons of info for you to read.
Well, like I said, I've kept guppies. I'm going to give them away soon, so if I were to just put the angelfish in the guppy's water, would the chemicals and things like that be okay? I mean, the tank would alreadly be cycled, and I read that guppies have similar tank conditions to angelfish.
Also, I have a rock that releases bacteria that eats the ammonia. Will that affect an angelfish if I get one? I also think that one angelfish in a 20 gallon would make the aquarium seem kind of bare. Would you recommend any smaller hardy fish speicys that can be kept with angelfish?
Oh, and thank you for the quick answer.
