Hey, I'm getting a peacock mantis for my dorm next year, and I was hoping I can use the filter I already have, a Tetra Whisper In-Tank Filter (20i). I know this is a SUPER noob question, but can I even use that in saltwater? It works great with my brackish Figure 8 puffer, but after a million google searches I can't figure it out. I don't see why it wouldn't but saltwater filtration confuses me to hell and back, so I could easily be wrong. Mantises don't need protein skimmers or anything fancy anyway, just some RO water and no harmful outside chemicals.
I've talked to several mantis people, and the general consensus tells me that it would be okay to house a 4 incher in a 15 gallon glass tank (upgrading later), with an acrylic sheet on the bottom (where the most strikes would occur), instead of going full acrylic. VERY few people have had problems in any circumstance, and I think it sounds pretty safe, but what do you mantis keepers think?
