Please help platy tumbling and swimming vertical
#1
Hello everyone, I'm new here and not long into fish keeping and I am desperate for help and advice
one of platy is was doing what u can only describe as somersaults and is swimming vertical as in head up, I have tried the pea method and some brine shrimp in case of swim bladder but no help.
Â
When I do a water change he seems to be worse for a while and then just goes back to the vertical swimming thing, he is still eating which is a good sign I guess.
Â
Any suggestions what this could be?, he has no marks on his body that I see
