For the past couple weeks I have been nursing a friends sick betta back to health, he had fin rot and an inflamed gil, the fin rot is almost gone and the gil is about 70% better than it was, and getting better every day. My friend said I can keep him since I got him healthy again

I bought him a proper home today, another 5.5 gallon, remodeld Zeus' home a bit, and got him 5 ghost shrimp as tank mates and algae eaters, so far so good, he will swim up and check them out but not even flare, they leave him alone.
