So heres one to chew on. I have a royal pleco and he found a home residing in one of those clay flower pots in my tank. I was feeding him the greens you guys had advised like cucumber, zucchini, squash, and so forth. He would only come out to nibble at night( thats a given after doing research). So it was time for me to do a much needed tank "cleansing" due to all the garbage build up on the bottom and such. Once I had finished and I'm guessing because the pot was moved literally an inch, he now wants nothing to do with anything I feed him, does not enter the pot anymore, and even posts on the glass ALL DAY LONG. Strange to me cause once I put him in the tank, he wasn't to be seen unless it was dark. What say you...Almighty Ones?!!
