Musket said:thanks brant, that's some good advice. When I add the driftwood, I'll try to make a few more caves on the other side of the tank as well.
When I cleaned the tank on Thursday, I saw both my little hiders. The tiny bumblebee is definitely a catfish of some sort, he/she was sold as a goby, and looked just like one, but now has whiskers. However, still doesn't really look like anything I've found on the net. And is at least doubled in size since putting him/her in the tank. At least I know they are eating well. I can find this one about 70% of the time now.
My clown pleco was on a tube, but now is hiding again. Maybe when I make the new caves and such I'll see him/her more often like you said.
Thanks everyone for all the input about the types of wood and where to find some. Much appreciated.
Does he look like this?
