my fish beauty had a hole in his tail and it has since opened and turned into a wrip. so no it looks like my betta has 3 tails and the ends of his tail is like wripped but like around like -()-()- i think thats fin rot and i read that has to do with ammonia? he has brown algae in his tank which i try and clean but it comes back fast withing a few days. what do you suggest? Epsom salt? Water changes daily? hiis temp is 72- 74 he has a 5 gallon tank with one plant and one decoration which both keep getting filled with algae thankyou!
