Hi everyone! I new to the site but not new to keeping octopuses. My issue is that I have only caught grown octopuses before, but have now acquired an o. briareus baby. Mantle size is approximately the size of a dime. My tank is a dual corner overflow 125, and I have had to make some adjustments so the little he/she can't get under to the sump. I have used fiberglass screening on the return pipes in the overflows themselves as this was much easier than attempting to prevent he/she from getting into the overflows. Does anyone know if this fiberglass screening is harmful in a tank? I have doubled the amount of carbon I am running to be on the safe side. I didn't find him in the tank again until last night. I waited 30 minutes with the lights off and then used a red head lamp for backpacking to scan the tank. I found him hunting, and then watched him return to his current den with a hermit crab. His movements were slightly twitchy, and he appeared to exhibit some involuntary jerks of his tentacles. When I acclimated him he was very fluid. Is this typical for this species?
