If it is a kind of big fish and a small bud it is fine but is it is on a tiny fishes tail and is this is a brown beetle with mabye red bumps on its back then yes, it is bad.
No its fine

Excellent for fishermen, people and other animals that eat fish. Not so good for the fish.
Yes
Yes, I believe fish is good for dogs. Fish such as salmon are good for bad breath and help to get rid of fleas.
Assuming a tank mate did not nibble the tail off, bad water chemistry (ph too low, for example) can dissolve fins and tails. or if a tank mate didn't nibble it off it could just be of bad age or something like that
Please describe the growth and where abouts it is on the tail. REAL ANSWER-It is ok if they have it, it is not bad, they are just growing. My betta fish has this.-Mii Bunny UPDATE* Is it fallling off?then it's tail rott.-Mii Bunny
