I've had velvet in my tank for nearly a whole year, I have three cichlids that i started out with and have not added to the the tank cos of velvet from the second week. I have tried everything to get rid of it, higher temp, salt, protozin, acriflavin, interpet no7, blackouts, huge water changes, removal and cleaning of all substrate. Nothing has worked and i am getting no pleasure in maintaining a tank that has ill fish sitting on the bottom or blasting themselves with the filter pump every 20 minutes to get relief, however they do seem to fight each other still. I want to stop the hobby as am getting no pleasure from sick, fighting fish however no one will take ill fish. I suppose part of me feels like I have every right to use euthanize after trying everything but part of me feels that though ill they haven't died so should continue to look after them however unenjoyable it is for me because I took the fish on!! What would you do?
