Outlook for sickly rescues?

[MissNoodle]

Rescued these poor guys. Tiny one has skin flukes and possibly internal parasites given his emaciated state. Two have torn up fins, one with just a stump of a pectoral fin.

I am treating with praziquantel and metronidazole for the parasites, and clean water for the speed up for fin healing.

That said, my question.

What's the prognosis on the stump fin? Since the entire barb is missing, will that grow back like the fin webbing would?

How old is the tiny one? He is literally only half an inch. The other two rescued with him are barely an inch, but still double his size.

I have the means to treat them, which is hard in my country given the ban on medications outside of a vet, so i couldn't just leave them. But given the poor condition of the tiny one, i will not be surprised if he doesnt make it even with treatment.

If the spine is missing, I think it's not growing back. Sorry. But I've had corys missing a fin and they led normal lives, as normal as possible anyway.

As far as age, I've seen some corys reach that size in weeks, less than a month, while others of the same species can take months to grow that size.

Nah no need to apologize, i appreciate the answer, even if i dont like it. Shame she wont regrow the fin properly, but shes got a home regardless. If i notice any struggle to get around, i can move her to a smaller tank so its easier, but i don't forsee a problem with getting around too much. Maybe just balance.

Ill keep my eye on the tiny one. Its not very strong, wobbly and almost skeletal with how thin it is. Ill offer protein foods until he fattens up more, while he is medicated too. I dont like how thin he is, makes me worry he wont make it.

All three of these are c. aeneus correct? The tiny one has yellow fins and darker body. He has a really good appetite.

Could the tiny one be:

Whats the difference between all these unnamed ones and aeneus?

Okay an update...

The tiny guy has finally put on weight and he has almost doubled his size. The stumpy fin one has grown the fin back, though the spine is still a nub within the fin. But shes looking really good. Both have coloured up and filled in.

The girl with the stubby fin:

The tiny one (on the right of the group)

But the middle one is remaining thin and pale.

Im debating another round of medicine to see if it helps, but i have my doubts and i dont want to waste a precious resource.

But otherwise they are doing good. Their fins have all healed up and now all thats left to do is grow.
