FrostiesFishes Posted November 14, 2020 Share Posted November 14, 2020 Hello ive looked all over the internet and in my fish health book for help with this issue and ive medicated the tank with a lot of different meds. the water is good I've tested it multiple times over the last 2 months. I've got angelfish, corydoras , plecos and a leaf fish in the tank. i started with a school of about 13 dwarf neons and had no issues. then added some black marble angelfish that did go into a qt tank for about 6 six weeks and showed no issues. so i added them to the 72 bowfront. and slowly I'm losing 1 rainbow fish at a time. I've medicated with the aquarium co op trio as well as many other meds with no results. but its odd that whatever it is just killing one rainbow at a time. so it makes me wonder if its not the leaf fish attacking them. he is about 5 inchs and the rainbows are adults at about 2-3 inches. tho I've never seen him attack them but I'm wondering if it happens at night. no other fish in the tank are effected besides the rainbows and like i said it happens one at a time. i did have a person on a rainbow fish forum say they've seen what im calling the (BLACK CHIN) before but found no cause or cure for it . any advise would be apricated Link to comment Share on other sites More sharing options...
