I added an in-line refugium that serves well as a copepod & amphipod breeding place. It also grows lots of cheatomorpha which they seem to benefit from.
My refugium keeps my DT supplied with pods, as there is never a time that I can't see lots of pods with use of a magnifying lens. I don't run filter pads that would block their return to my DT.
Still yet, even with a system ready environment....You will need to find a healthy (FAT) not previously malnourished Mandarin. Not every Mandarin you see at the LFS has had a healthy diet
Some can't recover. The one I got died.
even tho conditions were very good for it. It's the only fish that I have lost since I have had my currant tank set up.
Mandarins are considered a "difficult" fish to keep because of their feeding habits. You need to decide if you want to worry about them 24/7 before you get one. I personally won't get another one....simply because I don't want the worry of it in my tank. I like easy
Still love having a constant pod population for my corals & fish. Without a constant pod eater, I think my whole system stays healthier.
