I got three otos yesterday for a dollar each at Petsmart. I've been reading up on them. I was getting a bit of brown algae and in a day they've cleaned up most of it. I put a slice of blanched zucchini in for them tonight. So far so good. They are so cute. I've never had otos before but I never had a real planted tank before either. I didn't realize before doing some research that they are almost all wild caught. I just set up a QT that is empty, but did put them directly in my DT because it has plants and algae. That was a tough decision, but its done so I'm hoping it goes smoothly. Here is a picture of one of them. I like how you can see the otos reflection on the side of the tank.
