Thanks Wolf. I will mention here a bit about what I told you in PM. It's SO frustrating for me to post on fish forums. This is why I left another fish forum, because of the same kinds of reactions from the 'fish people'. I already know that technically my 2 fish need a bigger tank, but no one listens when I try to tell them that they have lived FINE in this tank for almost two years. I got the tank and fish when I knew nothing about them. I have learned a lot and one day yes I will get a bigger tank, but for many reasons I just cant right now, so I do the best I can with what I have. And my fish are happy and healthy with no problems. I can understand if they were dying, I would have to do something quick, but they're not! I like them and I like to learn about them but its just so frustrating when I just want a simple question answered and I get harrased about my tank. I had posted another thread last week in the picture forum and I got harrased there too.. so its just frustrating if anyone understands, probably not but I had to say how I feel and I wont say it again! Thanks for listening.
