i was at the fishstore the other day and saw an extremely active yoyo loach that was about 7”and decided to get it the next day(it was the only loach around this size so i didnt get a companion). ive had the loach in my tank with south american cichlids and plecos for about 16 hours and the yoyo loach has been chasing all the other fish around and has left a long scratch along my oscar with its tooth. i like the loach allot but i dont want all my fishs fins to get ruined. my cichlids arent exceeding 5” yet so i feel like the problem could go away in time. until then i wondered what i could do to reduce aggression and specifically if adding another loach would be smart and if i do so should i add a juvenile of the same species or something like an adult clown or skunk loach. let me know what you think i should do ill be adding more caves too
