I just got 3 seemingly healthy Ottos today. When I put them in the tank(after I had acclimated the bag) they went to the bottom and just sat there for a while sucking on the gravel together. A few minutes later though, they were zooming around the tank and they still are 25 minutes later!!! Is there something wrong or are they just exploring there new environment
PS. I thought that maybe the pet store sold me Chinese algae eaters but I checked my fishes markings and I highly doubt that they are CAE's but I am a fish noob! XD

as usual ANY information would be very helpful :]]
