I was wondering if it would be safe to put my betta in my 5 gallon aquarium. I've let him in there for a few hours at a time and he doesn't bother the other fish, just hides in the plastic plants. I'm more worried that the danios will hurt the betta's long fins. I have a bubble curtain tho, and I'm not sure he'll like the moving water. I'd have to get rid of the plastic plants too because they kinda have sharp edges.
