i just got back from break...i left my tank here at school with a cup of flies in it (only two frogs in the tank) and there's a waterfall running so plenty of humidity...and light on a timer. but when i got back today my GB auratus doesn't seem too well. he seems a little on the skinny side and isn't moving much at all...i had to poke him with my finger to get him to move. what could this be a sign of/what should i do? thanks for any help..
