Just recently picked up 2 jags 1" to 1.5" by themselves in a 90 for now pretty heavily decorated with rocks and driftwood. They hide anytime there is action in the room i.e. me feeding them. The food (NLS 1mm sinking pellets) just sinks to the bottom into the substrate. Is this because the tank is too spacious at their current size they seem lost in there. I've started with 2"-3" specimens before and never had this problem.
