I asked orginally in chat, and thanks for those replies, but I do have some more Q's.
1. Are they normally inactive during the day.. and most always when I watch anyway? I hardly ever see the little guy, and i think he's fun to watch!
2. How do i know if he is eating? I have algae discs that drop to the bottom of the tank, but all my fish (danios and gourami) pick at it. Granted, they don't do much damage to it, but they liked it. And about 20-40 min later i looked and it was all gone. Dunno if the pleco got it or if the others ate it all up.
Thats all for now. Thanks
