"It says" are just Google internet searches, I should've specified! Not dumb at all!
That's definitely good to know.. I may have to look into the buggers!

They may look pretty cool in my "cave" tank... Dimmer lighting, 3D rock background, they could look like eels or some kind of dinosaur.
I live in Arizona where it's just miserably hot ALL the time. I live in an apartment where there's poor insulation and literally cracks between the doors and windows, so any cold air is instantly sucked right out.

Therefore it's hard to keep it cool, so generally with full A/C blasting in the summer it's hard to keep it less than 85* in the apartment, so my tanks are normally around the 80* range. In the winter, sometimes it cools off. I'm hoping I can actually use a heater this winter to keep the tanks more stabilized!
I'm also considering otos, but I can only find one "kind". Aren't there multiple kinds of otos?
