Thanks dave

ive not been doing tos that long but ive had some bad luck with hex on fish. I have treated at least 7 cichlas that ive bought for HiH. Ive been using sera flagellol and salt with great success. When i treat with flagellol i do a 90% wc salt 3dl for 100L water and dont feed for 14 days just keep the tanks lights out and let fish fish be alone with medication. No wc or nothing.
Big cichlids are very prone to get HiH. Some species get it easier due to stress and water quality. Cichlas are some of these species. Ive got an mono that was so badly infected when i aquired it that it has never healed its holes but dont get any new holes and none of the other fishes its with gets any holes so it can be permanent but dont infect other fish. Hexamita is something all fish carries and its getting activated when there is a huge stress on the fish. Its a nasty thing that will eventually kill the fish slowly.
