I'm trying to keep the temp high, around 88F, but I don't have a heater small enough for little 2.5 gal, so I just screwed in the incandescent light the tank came with. The plants aren't looking so great after a week of this, but the fish is WAY more important. There is a very small amount of salt in the tank as well, but a very conservative pinch. Since the tank is so small, I don't want to send it out of balance. Water params are perfect. I have an extra airstone in there to keep the oxygen high. She *might* be a little better today! I'm very cautious about getting my hopes up, but it looks like the spots on her body are healing, and the spots on her eyeballs are mostly gone. However, the spots on her fins may have multiplied a bit, there are quite a few around the rims of her eyes, and her fins are as clamped as ever. She's still super feisty and hungry. I feed her in very small amounts twice a day. She gets a rotation of pellets, 2 types of flakes and dried bloodworms, plus little bits of pea a few times a week. I am certainly open to any suggestions!
I've been torturing myself to try to figure out how she could have gotten this, if maybe I messed up and somehow transferred it from the ex-pleco's tank, but then I remembered: At the same time I bought the sick ram, I purchased an Anubias nana and some Java Moss (from a different tank than the ram, but the tank did have some endler's and some kind of little cichlid. They didn't look sick, but then again neither did the ram!) for my betta's tank. I rinsed these plants off, worried about possible algae transfer, but I did not quarantine them. This must be where the ich came from. I have officially learned my lesson! I'm still doubting the betta will pull through, but maybe there's a glimmer of hope?
