6 month old 75g tank everybody happy no nippers with only 1 addition of 1 female beta a month ago taken from a tank devoted to african dwarf frogs. about 3 days ago woke up and all neon tetras (12) dead or dying. by the next day tiger barbs (8) started hiding and gasping. today down to 1 tiger barb 5 platties which seem to be uneffected
6 rosy barbs 3gasping will probably be dead by tomarrow.the only thing i see in common with some of the dead and dying is red blotches close to spinal cord between dorsal fin and tail when held up to light. looks like popped blood vessels deep in the flesh. all water quality and test ok, more than enough air. what's got me puzzled is when feed they almost jump out of the tank with hunger eating then the next day their dead. parasite? thanks for reading.
