Quick update for anyone following along.
1. Bought Tigger pods. Watched my mandarin's eye literally touch one of the pods and him not even think about eating it. Can't say for sure he didn't eat others but that was not a good sign for me. My firefish and clown both thoroughly enjoyed them though.
2. I've moved rocks from my sump to my display in the hopes of giving pods more hiding places.
3. I remembered I had a tank upstairs attempting to grow chaeto that wouldn't grow in my sump. That attempt failed but I ended up with a 2 gallon tank full of pods. I'm taking a cup full each day and throwing them into the display and sump hoping to kickstart the pod growth in the tank.
4. Mandarin is still alive, still quite skinny. I just took a close look at the glass in my display and actually saw a pod on it. I'm telling myself this is a good sign and that pods are starting to reproduce in the tank and keep up with the Mandarin rather than the other option of the Mandarin slowing down and dying on me.
Anyway that's the newest update on that.
