I have a betta fish that I got because I was in college and we are only allowed to have fish in our dorms. His name is Iggy and I've become extremely attached to him. I got him in late October and he has been fine since then, until recently.
Since we moved home, he's been extremely lethargic. He generally sits in the little ceremic home I have for him or on the rocks in the bottom of the tank. He barely eats anything and I believe he is loosing color and his fins and tail seem to be getting shorter.
I have done a lot of research about it and found a few possible causes of his sickness. His water feels chilly to me and I know that it is supposed to be around 80 degress so we got a thermometer that sits on the outside of the tank and it reads 80. We bought a heater for him anyway, but haven't installed it since the temp seems alright. We also checked the pH and it is around 7.6, which is high, but everything I've read said he has probably adjusted to it and making drastic changes will hurt him more than the high pH. I bought aquarium salt and we used that once and it didn't seem to make any difference. We've changed his water more frequently in an effort to help and after we change it, he seems better for awhile, but then he goes back to his old symptoms. I don't know what else to do and I'm extremely worried.
Does anyone have any suggestions?? Please help.
