Can fins realy grow back?

[AquariCam]

One of my Silver dollars has stumps for pectoral fins I've had her 2 years and honestly can't remember seeing this before so belive it is a recent occurence. She seem fine and is not bothered by other fish.

I have just finished a course of Melafix tm and was wondering if her fins can/will grow back over time?

While it is a possibility, it depends on how deep-seated the damage is, and how clean you keep the water.

Two of my eyespot rasbora had substantial tail fin damage when I got them two months ago. One of them has almost fully recovered, although I can still figure out which one it is. The other has partially regenerated the fin but its been slower and the one damaged fork of the tail remains split. So like ChilDawg said, I think it depends somewhat on the amount of damage, but assuming there is still something left at the base then yes, they can grow back.

My Angel went through a bout of fin and tail rot. It took two weeks for it took clear up, but after about a month it's fins have completely grown back.

Depending on the extent of the damage the tail may or maynot grow back. Had a fancy tail gold fish that lost major part of tail and grew only a stub. A channel cat lost top portion of tail which fully recovered.

My impression, and it's just an impression, is that the membrane bewteen fin rays or spines (depending) is quite quick to regenerate. Damage to rays or spines may be more permanent.

I have some Pearl Gouramis with fin membranes that are regrowing after being attacked by some minor ectoparasite (Costia or Trichodina or whatever) and I think some secondary bacterial erosion. The spines remained okay. The fin membranes are recovering now that I've eliminated the skin parasites.

Some professional fish rearing facilities fin-clip fish so that samples of the population can be evaluated and hatchery fish can be identified. This is permanent if the base of the fin is clipped clean (or otherwise removed). If the damage is above the base, the fin (rays, spines, membranes) grow back.

Thanks for all your replies.
Both fins are missing down to a 'stump' 1/8" so I don't really hold out much hope for them growing back. (I guess in humans that would be an amputation from the shoulder)
She doesn't seem stressed by this so I guess I shouldnt stress myself over it!

If there is a stump, it will most likely grow back. You can only wait and see. Let us know in a month if there is any progress.

in alot of instances of finrot, the fins do grow back over time. however, if the finrot has embedded it self far enough into the fins, then this may prolong the regernation period, if it does indeed happen. in the most severe cases it doesnt, which is a real shame as you can lose some lovely fish to it. your fish may be inbalanced for a while, but this should pass as it adapts.

Actually, with fin clipping, it depends. The complete removal of a pelvic or pectoral fin: nope, won't grow back. Most marking is done by removing a small portion of the caudal, anal, and pelvic fins; regrowth is possible, even probable with good water conditions and feeding. These areas are often clipped to use for recapture on population estimates, and the amount of regrowth can determine if a fish was indeed captured on a previous years estimates.

As long as the fish has either pelvic of pectoral fins, and a significant portion of it's caudal fin, it should be okay, though not as agile a swimmer. In tagged fish, there has been no documented detriment caused by the marking. I've assisted in marking graylings--we used a hole punch to remove a section of the caudal fin. There were several fish captured which had a portion of their pelvic fin missing, but with clear signs of regrowth, indicating they had been marked in the previous year.

what are some good meds for tail rot?
I think my two twinbar platies have it. They hang out at the surface of the water and swin backwards at each other--kind of odd to me. Sometimes they sit on the gravel. They still eat a lot, so I'm waiting to see more decay of the fins, but don't want it to get to far along.

i had a midas that bit the tail completely off of a convict and the tail has grown back perfectly

[Skittyfish]

I ended up having to use penicillan to completely clear up fin-n-tail rot.

Male platys swim backwards when they are trying to mate. Sure it's not this? The main symptom of finrot is the loss of fin tissue.
