Aggressive gold loach Nipping fins

I have one gold zebra loach and hes been pretty aggressive and semi chases the other fish, recently he ATE one of my zebra danios tails when he couldnt swim because of temporary swim bladder problems. Yes i said ATE. We put him in a hospital tank and have been letting it regrow. My danio is fine and swimming like semi-normal again he just has problems with lift off now because of his tail. Why is my loach so aggressive?? What do i do?

 

Is your loach the biggest fish in your tank momentarily because every tank will have an alpha usually the biggest fish in the tank will claim the tank as top hierarchy.As long as the loach is on top he will be aggressive toward smaller fish

 

No, I have 1 dwarf gourami, one honey, and one thicklip i also have like 2 pearl danios that are his size or bigger maybe

 

Hi, to me this sounds like what tends to happen when you keep social fish on their own, they behave differently to how they naturally would. In this case the loach is doing this by bothering other fish.

Would advise against keeping Dwarf Gourami with other Gourami, this is a problem waiting to happen.

Do you think i should get more loaches to ease this? My gouramis are very calm now, i have a planted 55 Gallon and the thicklip and honey seem to kind of “school” with eachother the dwarf does chase when they mess with his neat but other than that its all good now

 

Yes, ideally you would want to keep a few more as in 6 or 7.

 

Its probably best to keep the loaches in a social group without other fish except maybe some robust dither fish like large tetras/rasboras/barbs. They are more entertaining and satisfying to own than most other fish. I'd find out what species you have (latin name) and read about it on LoachesOnline and SeriouslyFish.

Melafix has helped my fish regrow fins fast in past
Idk how new which fish are to the tank but did you try rearranging the tank decor the idea is it changes things up so the aggressive fish doesn't know every single spot to find his victims so easily lol also I've had luck by adding tall plants so there isn't a direct line of sight from across the tank so the aggressive fish will have more trouble getting to them and hopefully ticked off less cause he doesn't see them as easily just an idea..
