My son was gifted a blue Betta six days ago; here is the CURRENT situation:
tank size: 1 gallon
heated: yes - 76 degrees
number of fish: one
age of fish: over a year for sure - purchased at local pet store
water: treated with Nutrafin Aqua+Plus and aquarium salt
Food: Omega One Betta Pellets
We received "Bloowie" last Sunday; I knew right away that the tank was too small, but I didn't want to stress the fish any more than necessary since we had to transport him home (half hour drive) and I figured that was stressful enough for one day! So I let him be for a few days. He wouldn't eat. I was told by the pet store that this was normal - he was sulking from transportation.
I figured that the water was too cool, but couldn't deal with that situation until yesterday (Friday). I purchased a heater, new gravel, a plastic plant so that he could hide and rest, and put this all together in a gallon pickle jar (it IS bigger). I noticed that this pet store kept their bettas in tiny bowls...sigh. I spent the entire evening acclimatizing him to the new environment, and he seemed very happy!
Above image shows the happy fish around 9pm Friday night.
This morning, he didn't want to come out from hiding in the plant. When we DID finally see him, it took me a while to notice that he has fuzzy white patches on his sides (both). It is difficult to see unless the lighting and angle are both right. I have tried taking pictures (see below).
The pet store says it is a fungus, so I will go purchase something this afternoon. Any advice is welcome, but please understand that I'm not going to invest $100+ in a larger tank until I can afford it, which won't be for another six months.
Did I do something wrong with setting up the tank? Was he sick before he came to us? Do I have to take him out to treat him? Do I wash everything in the tank and start again (if the fish survives)?
This is all so stressful!
