I started a fish tank for my kiddos last week. We let the tank "cycle" for 24 hours then added 5 fish. Two tropical little orange fish (platties?), two neons, and one betta. Up until yesterday, the betta flared at the other fish, they all swam around, and they all played. It was awesome!
Yesterday, our betta (Rainbow Brite) nested in one of the plants in the tank and hasn't moved since except to drift to the bottom of the tank. :/ I had the tank water tested on Monday and the fish shop said it looked awesome. Rainbow nested Wednesday and had drifted to the bottom of the tank by today.
What should I do with this fish? My kiddos love her, but after reading all the posts here, I wonder if I should have let other fish "season" the tank for awhile, then added a betta later.
