Hello, I'm new to the forum, but no where new to Betta keeping. We had taken a break from betta keeping for about a year after my last boy, Shadow Storm, died. He was a Wal-Mart betta I had for 4+ years. For years we had bettas in just about anything that would hold enough water in our house.
I took a break, but fell victim to PetCo's trap of baby bettas. I know I should not have done it, but I bought one. Some of them were already failing in health and I knew they wouldn't make it much longer, I spotted one that still looked fairly active and healthy and possibly a slight blue tint on it's other wise colorless, less than 1" body. I housed it in a 1 gallon tank with a heater. I only fill it less than half way so my baby doesn't get lost and have a hard time finding food and air. I threw in some plant bulbs to grow in the tank as well.
I've had my little one about a month now and I'm thinking it's a veiltail female, but it's going to be a very pretty one. The blue tint I thought I initially saw is developing more and the fins are developing a reddish color. I had been crushing the PetCo brand pellets (I got them because of the higher protein content and because they are smaller than any other betta pellet), now my baby is big enough to eat them whole. I also gave it a little freeze dried bloodworms and recently flightless fruit flies. I discovered that one by chance when feeding my teeny tiny toad, I threw 3 flies in to the betta tank and it devoured them. I also think it was picking/grazing stuff off the plant bulbs.
