So I bought a Figure 8 from my LFS and the guy that owns the store doesn't have a lot of knowledge about them so he was no help at all. The first fish I bought from him was a plump, dark back, very white belly puffer, his name is Zeus <-- I love him a lot. I have had him for a month now and we have gotten to the point where he eats out of my hand and greets me, I did have a little trouble with him in the beginning; he wouldn't eat and would bump into everything almost like he couldn't see, I changed the water and it didn't help with anything, so I bought another puffer (Hades, who I have questions about later) and a few small snails. My idea on this was maybe he didn't like the food I was feeding which was blood worms and brine shrimp, and maybe Hades would help him find food, but my thoughts were wrong and he still wouldn't eat. I then noticed Hades picking on Zeus. After searching the internet I couldn't find anything. I then noticed little cottony white film over Zeus's eyes I then went to my LFS and told the owner all about it, luckily he knew his fungus

! So I treated my entire tank with Jungle Buddies and have had a lot of results, Zeus is now eating

, but Hades will not

. He almost seems jealous and won’t even look at food, but now he tries to go after Zeus. Is it normal for this behavior? Another question about Hades, when I first bought him I noticed he had a lot of bumps in his stomach, they do not look normal to me. (Since he was the last one I couldn’t not buy him.) but when I feed him the bumps blend in with the rest of the belly but when he hasn’t eaten the bumps are very noticeable. I also noticed when he was eliminating waste that it was coming out in huge chunks

, I feed them brine shrimp mostly and it looked like the full brine shrimp was coming out! Anyone have any ideas what could be wrong?
I have 2 female feeder guppies and 4 fry guppies, who are all going back to the LFS. 2 small snails, and the two puffers Hades and Zeus.
they're in a 10 gal, sorry I know that's not enough room hence why I'm taking the guppies back; but I'm also planning on a bigger tank soon, the water temp is 76 degrees, nitrates nitrites all that are good, they are in a brackish tank, water current is at a slower pace. Plenty of hiding space, I sometimes can't even find them. Any ideas on Hades?
