Hey all. I have a dilemma. I have a 50gal tank with one Lepidota, one Firemouth and one Flowerhorn. I recently had a vacation of about a month. When I left, the fish seemed fine. They looked good and ate well. They were at the time becoming increasingly shy however. I mean, when I bought the pike 4mos ago, he was constantly at the glass begging for food. It was awesome. Now he, and he and his tankmates hide all day, and act truly fearful of all things human. They were without a light for the last two weeks of my trip, but reportedly still ate/showed some interest in food. When I got back, it was a different story. I fixed the light and now they are even scared of that. The water they had been in was very hard with a pH of about 7.8. I understand thats not appropriate for these fish but It didn't seem to bother them. I have since begun importing better water, slowly changing over to the softer with a pH of about 7. It's the only thing I can think of that might be making them upset. I think they are healthy but they are just so scared of everything. I am new to the hobby, but have fast become infatuated with my fish. Has anyone ever observed this behavior? Any ideas?
