Apologies, I just posted this as a 'reply' accidentally, and am now posting as a new thread because I'm desperate to get some assistance with the problem. (My first attempt at posting anything on a forum...)
Hi! I joined the forum because I'm concerned about the health of my beta... He seems to be quite ill... I went away on vacation for just over a month, and while I was gone, he moved to a friend's house. In that time, he didn't get his water changed, and was fed about 5 pellets, twice per day. I know the transport itself must have been stressful, so thought that may be the problem. However, he's been back for about a month now, and seems to be getting worse instead of better. The front of his body is bloated quite a bit, and he simply lies at the bottom of the bowl. He is also extremely pale around the bloated area. I spoke to someone at the store where I bought him, and he said to give him 1/2 of a pea - that if he was constipated, this should resolve the problem. I tried this twice, but to no avail. The bowl he is in is specific for beta (just a glass bowl that has a light attached to it). It has no kind of pump, etc. to put oxygen through the water.
I feed him about 4 or 5 pellets once per day. I typically change the water in his bowl once per week. I put in bottled water at room temperature. Note, I live in the Caribbean, so room temperature is between 82 to 86 degrees.
Does anybody have any suggestions? It's hard to tell if he is alive or dead, he is so still, simply laying at the bottom. When I feed him, he struggles to get to the top, then quickly sinks back down to the bottom.
Having read some of the posts, I'm wondering if perhaps the water is a problem? (Note, we bought the fish in Aug 2007, and he was fine in the same kind of environment until I went on vacation August 2008.)
If anybody had any suggestions, I would be most grateful.
