I just started stocking my 55 gallon. Friday night I added my first fish, 6 congo tetras, 2 dojo loaches, and 1 rubber lipped pleco. Since he's been added my pleco has spent almost the entire time in hiding. He likes to stay under the driftwood or his favorite spot is inside a small fake hollow log I have in there. Is this normal? Will it just take him a while to get settled before he starts coming out more? My water parameters seem good. Ammonia 0, Nitrites 0, Nitrates <20. I'm not really worried about his health, just hoping that I can expect him to come out of hiding more often in the near future.
