I have a red potato puffer that I got in July and she was about 1.5” and she is close to 3” now. I dewormed her when I brought her home and she is the only fish in a 29 gallon planted, sand bottom tank with regular water changes and good water parameters around 77 degrees.
She has been doing amazing almost always out and about or hanging in the sand. Not scared when you are around the tank or doing maintenance. I have never changed anything in the tank other than add some plants. Eats ghost shrimp, red wigglers, meal worms, black worms, baby sword tails(raise in a different tank) and have tried crickets a few times. Can only get her to eat live food but have tried frozen many times.
A few weeks ago she started to glass surf on occasion and it’s been increasing. More concerning is after she would take one food item from the tongs(usually gets 2-3 depending on size) and I would try to give her the second item, she would darken in color swim off and frantically glass surf like she was trying to get away sometimes splashing at the surface. She will be weird for several minutes so I will just leave her alone as I don’t want to stress her any more. I have started feeding her one item once or twice a day now since she will freak out sometimes. I haven’t done anything differently other than getting ghost shrimp every other week and not every week as they have been harder to find. nothing has happened in the past like getting hurt, sick, stuff falling in the tank, etc. Now when I come up to the tank she is a bit more reserved and will sometimes back into the plants a bit but she will then come back out after a few seconds but not every time. The rest of the time she is just swimming normally or in the sand. Any ideas on how I can help her out? Is she being a moody teenager? If you need more info about anything please ask. Thanks!
