Thanks OC!!
SK, my fish are healthy, colorful, eating, and my Platies are reproducing (but aborting due to my mistake of putting them in a breeder net. I'm putting the fry in my other 10 gallon tank first, raising them, and giving them to my friends, I MIGHT think about keeping some, but right now I just want to experience my first batch of fry). I think that I might keep the Oto for the experience. Because, even though it's a more safe and humane thing to do, if I take the fish back I won't learn anything then if I keep it and see what happens. Truth be told, the Otos were a, what do you call it?- urge (or something) to buy. They were so cute that I had to get them. That was my second biggest mistake ever. My first, was when I put a male silver sailfin molly and a female black molly in a 1 gallon pitcherwith nothing but gravel in it. Sure they died, in a record time of 4 days. I decided that I was going to learn from my mistake, so I did not take them back for anything (more fish, or store credit). I'm going to take my sweet time with this other tank. My friend really likes Glofish too, so I might think about putting Glofish in the tank instead of a single Betta. *sigh* There are so many possibilities!! But, I'll consult her about the Glofish. At least that way, I won't have to wory about having a picky Betta. I can be fine with the food that I have.
