No it's see-through. I feel so bad for him in his bowl
I would get him a 2.5-5 gallon tank. If he was agressive to your other fish, then it might not be a good idea to let them mingle. And bowls are just so cruel. I would go out and buy him a nice tank so he can be happy and away from other fish. How long did you have him in your big tank? It might take him a couple of days to get adjusted. If yu only had him in there for a little, it wasn't really a fair chance.
