I have an injured cory cat and need some info

    Hi. I have an emerald cory cat that is missing his entire tail fin! I'm really not sure how it happened, just that I saw him one evening with a bloody pectoral fin (or at least it looked like blood) and then about four or so days ago I saw him after, it had been probably a week, and he had a stump for a tail. It looks like now it's starting to grow back but now I'm wondering if he might be better off in my cycled five gallon alone? The tank he is in now has medium sized gravel, where the five gallon has sand. I don't want to lose him! He's one of the original fish added to the tank almost a year ago. Should I leave him? Move him? He seems to be doing alright and I wouldn't bother except I know cories (THIS STUPID PHONE!!!) like sand. There isn't anything sharp in the tank that I can see anywhere and I was wondering how... I recently had a bad bout with ich but that wouldn't remove tail fins, would it? I do have a large angelfish that recently developed a taste for live fish though (unintentionally fed him one of my guppy fry) and wondered if he was bullying the cory. Before he wasn't too aggressive but now it's much worse.

    Is it just the angelfish and the cories in the tank?

    I'd move him into the 5 gal for a temporary quarantine and do large, frequent changes to help him heal. Meds may be needed - can you attach a pic?

    What size tank and what other tankmates do you have? Can you take a picture of the cory? Angelfish aren't normally aggressive towards corys.

    If the gravel isn't sharp, I don't think that would be the issue. I wouldn't move him to the 5g though as being alone there may make him more stressed. I would keep the water very clean in the tank he's in. What are your water parameters - pH, temp, ammonia, nitrite, nitrate?

    I'll try to get a pic of him. I also found another thread with someone with the same issue: ich, columnaris, cory missing tail fin and red other fin. Only difference were the fish species involved and the red fin on the other cory was the dorsal.

    No, the gravel isn't sharp. It's a 38 gal euro tank. The other tankmates are as follows: a trio of mollies, a trio of adult guppies, a brand new trio of plume tail platies, a large angelfish, a medium-large pleco, a medium bn pleco, the cory, and around eight small guppy fry. The parameters are:
    Ammonia -0.25 ppm (Only because there has been a lot of decaying plants and fish in the water)
    Nitrite - 0 ppm
    Nitrate - 20 ppm
    Temp - 78 degrees farenheit
    PH - 7.4

    I got a pic but need to figure out how to upload it.

    I'm not able to view those links.

    Can you also post your water parameters as well as what you're feeding him? If he's the only cory, I would get at least 5 more friends for him (same species).

    I updated my last post to have water parameters. He is the only cory currently, but he did have a school of five others before. The others all died /: I was waiting to see how he did before getting any more. I feed him Cobalt Aquatics tropical pellets and brine shrimp pellets, as well as the omega one flakes and cobalt color flakes that float to the bottom.

    Still don't see a photo. Try doing a couple of large water changes a couple of times a week along with a good gravel vac to pick up decaying plant matter once a week. Did you find all the dead fish?
