Goldfish Tank Mate/size Of Tank

[megan16]

I have yet another goldfish question, Right now I have a black moor in a 20 gal. tank and was wondering if a weather loach would be to large to go in the tank with it. I'm getting my brother an aquarium for a present and I'm trying to figure out fish that could go in the tank with it other than other goldfish, so any suggestions would help. Water quality is not an issue, I have had him for two years without any problems.

I wouldnt add any other fish unless they are quarantined first.

If you are getting him a tank for the moor then tell him that you want to also give him some more fish and use the old tank for quarantine.
You can get two loaches as they like company and maybe 4 -6 white cloud minnows. Loaches though are masters at escaping tanks so make sure all exit holes are blocked.
