Put Luna on the side that's a little rougher. She's less likely to rub against it trying to get to Turbo. Males will swim closer and flare a lot. You can also try putting cabomba in front of it so they can't get as close.
I posted a new thread on what happened in Betta Fish Diseases and Emergencies. So far, it seems to have just been stress. And he must be losing more slime coat again this morning.. Do bettas lose slime coat after being significantly stressed? Or can it just be a random thing? Anyway, he's still in the hospital tank. I had to re-empty the ten-gallon last night to put the hospital tank back in there..at around two in the morning... And, worst of all, I couldn't use my fish bucket!!! So, I had to use his water change container.. And I had to scoop out about the equivalence of 1/4 of a gallon..walk to the kitchen...pour it out....walk back to my room...scoop out more water...walk back to the kitchen... And so forth and so on. -_- But he's pretty much gotten his color back, from what I can see. I was so excited about putting him back in his ten-gallon.. =( -Sigh-
Turbo's back in his ten-gallon! Still not looking any better. :( I saw more white on the tips of his fins, but different.. So, I guess, even more slime coat coming off... =( But his fins still look bad.. He has more space, though, and I need to get more stuff for his tank today so he'll feel more secure. I'm experiencing some trepidation when it comes to adding Luna. One part of me is like, "ADD HER! You knowww you want to!!! You've been waiting so longgg!!!".. And the other part wants to wait until Turbo's fins seem to be getting better..
The white tips are on the ventral fins and have been for quite some time. On the other fins, excluding the pectoral fins, white stuff will appear.. And go away.. It usually doesn't last long at all, so I've been thinking it was just slime coat coming off. He's not as active, but he's more active than he was in the mini tank. Maybe, he'll get more active once I get more cover for his tank. It looks kind of bare in there, honestly.. =[ I'm sure it makes him feel insecure, and he probably doesn't want to move much and draw attention to himself when he doesn't have much cover. Maybe?
