I purchased a new tank for my 3 year old betta some time ago. He's currently in a 1 gallon Marina Cubus tank and I got a 2 gallon Spec Fluval tank that has a small filter.
I've been nervous about moving him to the new tank (it's literally been sitting around my office for a year already
) but he was starting to act a little lethargic so I decided to make the move today.
I set the whole thing up and made sure the temperature was the same as his current tank (~73 degrees). I soaked the new rocks overnight and made sure they were clear of any debris. I set the filter as low as it would go and added part of the water from his current tank and some fresh water as well as a little bit of aquarium salt and water conditioner. I acclimated him to the new water in a baggie and eventually let him go.
He immediately laid at the bottom and seemed to be struggling to breathe. I gave it a half an hour or so and he started to look a little bit pale so I pulled him from the new tank and put him back in his old one with some aquarium salt. He's 1000% better now, color is back and he's eating/swimming around.
Did I do something wrong? I did some googling and it seems I should let the tank cycle for a week or 2 before adding the fish so I'm going to do that but now I'm afraid to ever move him again. Should I just leave well enough alone in the 1 gallon tank? He's gotten bigger since I first got him and I want him to have enough room to enjoy himself. Any advice would be appreciated. Thanks!
