I have a single balloon belly molly fry in a 2.5 gallon tank, she's about 3 months old. I am going to be out of town for 8 days, and I know that young fish need to be fed more frequently than others, but I'm hesitant to put a vacation feeder in there due to the small size of the tank. I could potentially take it with me I guess, although I didn't know if that would be a huge stress on the tank/fish or not. I'd appreciate any suggestions- thanks!
