i have a 13" ck and last night i added a 6" tinfoil barb, he is in no danger of being eaten but all night he got chased, by this morning a lot of his scales were gone and his fins are cut in strait lines to the body. can stress do this so quickly? i think he is leaving him alone now that territories are established. what time frame should i expect for healing to take place and his stress go down. is there anything i can do to expidite his healing.
