I get burned out on occasion but it doesn't typically last long, sometimes just visiting a forum and talking with other people helps because there just isn't anyone in my offline life that can really relate to me. I never get bored of fish and never want to get out of the hobby just frustrated. Frustrated with water changes, aggression, failed breeding projects etc. Probably what bugs me most is how unorganized it all is. I think having an organized fish room would help me a lot. I have tank scattered all over the house and each one requires different steps in order to do a water change. It is a PITA. Sometimes I think I need to downsize but every time I look at all my fish I realize there aren't any I want to part with. That plays a big part in loosing that burnout feeling, just sit back and enjoy the fish.
