I thought it would be fun to get my 5 year old gs a small tank with a betta. I have 2 tanks, and I'd take care of the small (5 gallon) tank with the betta. He would feed the betta on the weekends (supervised of course). SO off we went to the fish store and picked out a beautiful blue, very friendly betta. (I've only had one other fish that friendly), my gs named the betta Thomas, he's into Thomas the tank engine.
Last night I had to break the news to my gs that his betta passed. I told him Thomas was now in heaven with Jesus. My gs was absolutely
inconsolable. My daughter had to take him home, give him a bath and try to explain to him what just happened and why. All he kept saying was "why mom, why." He didn't sleep very well last night and is still sad this morning.
I'm so sad, we could have gotten a replacement fish, but he's smart and would have known right away. Next time I buy him a zebra or molly along with 5 or 6 of the same fish so he doesn't know which one is his.
