We added some Cardinal Tetras (6). After a couple days, they seemed to be doing fine and the water was testing okay. We took our existing stock from our 2.5 gallon (2 algae eaters and 4 guppies) and added them to the tank. On a trip to Wal-Mart, my daughter fell in love with a betta and so we added him as well. At lot to add at once, but so far so good.
Now today, I wake up and find only five Cardinals. Searching for the Betta and find that he's got something sticking out of his mouth. So, apparently he ate one. They've been together for a few days and I've been feeding freeze dried blood worms - so you'd think he would have been not hungry.
I'm going to get a pic to see what you guys think I need to do with this Betta. Does he need to go in the 2.5 gallon by himself? Do I need to try to catch him and pluck the remains from his mouth? Photo coming soon.
Oh, the excitement of a "natural" habitat...
