So my Stendker discus arrived on Thursday via UPS shipping. I didn't have the tank setup or know until the night before that they'd arrive. I cleaned the tank thoroughly siphoned every inch of substrate until the siphon ran clean when pushed into the substrate which totaled out at 4 100% water changes. They arrived in good condition but wouldn't eat. Thursday, I tried some basic NLS flake and they turned their nose up at it.
I tried morning and night, for 4 days straight using several different foods and they'd look at it and swim away...
And then today, BOOM. They ate. Messy, spitting the food out and then eating it again but they ate. I was so elated that I decided to film it and on watching the replay I saw something really unexpected. One of the discus started "shimmying." It can't be displaying, right? They haven't even colored up yet and are two young but I've got it on film and the shimmy is undeniable.
Any advice or thoughts?
