So after about 2 months my water has now been cycled and is very stable. I have a cory cat and Its fins are decaying between the spiky parts. I do know that my gourami tortures this poor fellow all the time but I am not sure if he is responsible for the fin damage or not. It is only on his top fin and tail fin, but the tail fin looks kinda fleshy but it is really hard to determine if it looks like damage from the gourami or not. I dont know what fin rot looks like so I am not sure what it may be. If it is fin rot how do you treat it??

thanks a lot
 
If your cory is alone and you have some extra space I would highly suggest getting at least 2 more of the same. they do so much better in groups. While stress wouldn't cause fin rot lack of stress can certainly help a fish's immune system recover from it and a group of cories will reduce their stress (espceially if a single is getting picked on).

Since the spikes are still present then fleshy bit should grow back fine. I would suggest lots of fresh water. Daily water changes will promote a healthy environment in which the fish can regenerate lost tissue. Feeding quality food will also help, especially sinking pellets for catfish.

If their is no sign of regrowth after a week then you may have a disease in the tank. Look for other signs and also do a search on the interet for fin rot and see if you can find some disease websites that also have pictures.
 
Okay so I would definitely say that it is fin rot but My water is in good condition I have been testing it twice a day for a looong time and also have had it tested at LFS every time I go and it has been good for some time now. I have 2 corys in the tank right now the biggest is about 2.5 inches and he is the one that has the fin problems. the other cory is about 3/4 inch. The fish is acting totally normal. Can I put something in the tank to help his fins out? Also what type of food should I feed the corys?
 
I feed my cories a variety of pelleted foods (a different one each day) and once a week frozen blood worms. Always buy the smallest amount of food possible so that it is a fresh as possible. Old food (say over 3 months) should be gotten rid of in favour of fresh food.

Otherwise, large water changes is your best bet to regrowth. Adding something like melafix may help but isn't needed.
 
do you mind my asking what do you mean by 'good' as regards parameters, and what are you (and your LFS) testing with ?
 
I have been testing with an API Freshwater master test kit and my LFS uses quick dip paper strip indicators. Just tested my water and parameters are:
Ammonia-0ppm
Nitrites-0ppm
Nitrates-in between 0 and 5ppm
pH-7.0

I was also wondering If I should be adding salt when I make water changes? My LFS told me that I should be but I also read on here that certain catfish are extremely sensitive to salt and I didnt know if corys fit into this category or not? I really need to do something fast because he is developing a small red dot on his body right at the base of the tail fin. I dont know if I should add some chemicals or not, I'm sure thats what the LFS will sell me but I trust you all way more than them. I dont have a quarantine tank and I dont know if chemicals will affect my other fish or not. i have in my tank as of now: The sick cory, 1 small spotted cory, 1 dwarf flame gourami, 2 yellow platies, 2 sunburst glofish. Also I was wondering if the cory could be stressed from not eating enough? I feed the others wardleys total tropical flakes and dried baby shrimp sometimes. Do you think that he gets plenty of food from that or is he maybe undereating because I have never had any of the pellets? Thanks so much for your help
 
any suggestions?? I am about to head to LFS and see what they say but I'd rather hear your suggestions first.
