my leo has decided to go on a food strike.. this scares me... because a couple days ago he was eating like crazy, tested the water its fine the other rays all eat (histrix, and two motoros) only thing that changed was i put some balas in and a poly, the leo ate the poly and hasnt had a meal since, im woundering if the poly didnt agree with his stomach? but it has been 3 days since his last meal... should i be getting worried?
