Got one last weekend about 2 inch long. Tried mealworms, nothing, floating pellets, nothing. It took some feeder fish, and then I chucked another 3 feeder fish but it only took 1. The other 2 is still alive and it's been 2 days since the aro last ate. Remaining feeders too big? Or does filtration system affects its feeding? It's still quite jumpy.
