My boy, Fish, has been very lethargic the past two days, and has also managed to shred his fins. He is a veil tale, and his fins were in good condition when I got him last weekend.
His fins are shredded, and his tale has holes in it. I took out his plastic plant last week so he wouldn't get hung up on it, and have moved his rock so he won't get caught after noticing the fin damage.
I started treating him with Bettafix last night. Does this sound like a disease? He is usually a very active fish and he's been spending a lot of time asleep on the bottom of his tank. Dad said he was sleeping on his side last night.
If you don't see an improvement within a few days, use Maracyn-two+Maracyn in combination. What I usually do is fill a small cup with 20tsp of water, than add one pack of each medicine to the cup and let it dissolve. I than add 1 tsp to the hospital tank with the fish undergoing treatment once a day for 5 days. I also add a bit of bettafix/melafix to help promote fin regrowth. I use a turkey baster to suck up any poop or uneaten food that falls to the bottom of the tank as well to keep the water clear. After the 5 day treatment period, I do a 100% water with treated aged water and gently reintroduce him (making sure the water temperature is the same). If the finrot acts up again within those two days, I repeat the treatment.
But you have to be careful, because the longer your fish is exposed to medicine, the weaker his immunity to the disease becomes. So you'll have to preform water changes more frequently if you have to treat him for a long period of time (like Shota ): He has kept having relapses for months... so he's very prone to getting finrot...)
I'd like to test a product called Gel-Tek Ultra Gro VX which is supposed to strengthen their immune system, but it's pretty much unavailable in Canada, but if you can find it, I'd suggest you try it. I read some good reviews about the product.
It sounds like bacterial finrot, if it were fungal, you'd see a white cotton substance on his fins. Also, shredding is generally associated with bacterial, Fungal will eat away at your fish's fin in a consistent manner while bacterial will attack in random areas of their fins.
The fins first appeared to have tiny holes in them, then proceeded to rip lengthwise. Now the bottom half is brown and he has whiteish spots over his bosy and small "swimming" fins. She's not moving much and isn't eating.
