What Pure said...
They've actually gotten along pretty well surprisingly. The Red Tail's how brought it upon themselves to not only clean the tank but clean other fish, lol.
Besides, the LPS said the Red Tails are peaceful, and my plecco is a "small" one.
HAHA. I'm just happy we didn't listen to them and get the Irridescent.
You should all be happy though they told us about a fishless cycle, not quite the same though.
They just told us to let the tank run for a week.
