Hi so I've had a powder blue dwarf gourami for a couple of months now and I'm worried about him. I feel like he gets pushed around by this new filter I got (the old one broke) and he is already really stressed and injured himself by swimming around way to fast in a small fish bowl (temporary home for them when I first moved and had to get some new things for the tank but didn't have the money). He had bruises on his side which I managed to heal with the help of prime and now he is back in the 20L tank with a new filter (Aqua one 101F) and also an airstone. He hangs around the bottom more often than not but still likes a good feed. Actually he is a pig so let me know if that's normal. He also hates light and whenever I try turning on the LED overhead light built into the tank he goes ballistic and if I kept it on he'd probably accidentally kill himself. He seems so stressed and the only time he wasn't was when I had a live plant which just died due to not being able to turn on the light!!! I have a large fake one now but it seems to stress him more! I do have a heater which is on 26.01 atm and the ammonia levels have seemed to stay down the only that is that the PH stays high between 7.8 - 8.2. I have been searching forums constantly with every thing he is doing and i can't find anything. There's just something wrong but I don't want to remove the filter either as I think that's part of the problem because it keeps the tank clean. I'm sorry if this is all over the place but I don't know how to explain what's happening because so many things are going on. If anyone can help PLEASE DO.
