Well, the baby Platy is still alive. He is still in a HT, but after 3 rounds of MII and 14 days of Rid Ich+, I stopped the meds as they made no difference. He is eating a little bit everyday, but here's the weird part - the latter 1/4 of his body is almost in a Z shape now. He mainly stays on the bottom since it's quite an effort for him to get to the top. He has no sores or ulcers or any other signs of distress.

Now, the question is what if he just stays like this? Can he live a normal life with the curved (now z shaped) issue? If so, can I ever put him back in the main tank?

I've come so far with him, but don't know what to do with him now.
