Hi all, I have a Trigger Platinum (20 cube) sump. The front area of the sump is designated as the refugium area. In this area I have mineral mud about 2.5 inches thick across the entire bottom and above that is free-floating cheato that takes up a good amount of space. That area has a large population of amphipods of various sizes, some as big as small termites, but No other livestock except some pineapple sponges I recently ( 3 days ago) bought a bottle of "Tigger Pods" they looked orange in color, and were very active in the bottle. I floated the bottle for about 20 minutes, turned off my return pump and skimmer, and released the pods into the refugium area. Using a flashlight I checked on them several times over the next 3 hours and saw MANY of them swimming and jumping about., I wanted to make sure they had enough time to get in the cheato or mud before turning the return back on. After 3 hours I turned on the return and went to bed. FF to tonight, I turned my return of to feed my DT and decided to use my flashlight again to see any pods moving about. To my surprise, I DID NOT SEE A SINGLE ONE and I looked for a good 10 - 12 minutes holding the light still and watching all over. I could clearly see the amphipods scurrying about as usual but Zero copepods Is it possible they all went into the mud? Do amphipods EAT copepods?? I wanted this area to be a breeding ground for copepods. Does ANYONE have a similar experience or any info?
