My boyfriend found my baby betta (about 9 weeks old if that when I got him) dead today. I rescued him from a chain pet store and he was in bad shape (so bad they gave him away for free) but survived exactly 1 month with me today, his fins were starting to grow back really nicely and he was growing a lovely little half moon, he seemed really happy.
A few days ago I moved him to a bigger tank and I think the stress of the move was too much for him. I regret changing that tanks now and I'm really upset but I'm glad I at least managed to give him a month of pampered happiness and probably prolonged his life a lot longer than had he remained in the pet store.
I will miss his cute little face, and how shy and afraid he was at first till he got to know me.
