ok, to get it out of the way, i understand basic octopus requirements (ie. SG, nitrogen cycle and appropriate levels, general temp requirements, cycling for 3 months etc etc). i've been doing my homework on that stuff. i also decided not to squeeze mine into a 6g nano i had up and running. i work at a pet store (it sucks by the by) and find myself thoughorly pissed when people want to put oscars in 10g tanks, or think "nemo" looks cool and they wanna put him with the 10 fancy guppies, goldfish, and "allergy eater" they have in their 20g starter tank, not realizing "nemo" is from the ocean. or the people who have a 55gal tank full of tangs, knowing full well many of them already aren't getting along, and thus decide to fit "just one more" into the tank b/c they want to see the fireworks erupt. so, i do not wish to be "that guy" when attempting to keep octopods. my thoughts thus far were to use a 30g (just b/c i have a 36" stand and PC lighting unit ready to go from my 38gal...not using the 38 b/c i think it's too tall and not enough gas exchange will occur). i thought about having it drilled so i could include a sump/ refugium. i don't want any equiment in the tank, just the overflow, and the return. i am not very DIY and that is part of my hesitation. i'm curious to see how others on this forum octoproofed their set up. i guess what i'm looking for is step by step instruction for how to turn a glass box into a "maximum security containment facility" for captive escape artists. i understand the need for a tightly fitting lid. i just don't want to see this thing find it's way to the sump or random pump impellers. other questions: would it be possible to house a dwarf species in a refugium environment (ie, mud, liverock, macroalgae, copepods, etc) that was plumbed to a reef setting assuming measures were taken to prevent ceph assimilation into the main tank? being nowhere close to the ocean, and having no live foods other than ghost shrimp or spending hundreds on "clean up crews" (ie hermits and snails), can i opt to try frozen foods? the zoo near me has had a mimic for a few months now and has been feeding a wide variety of frozen foods.
