I will be going away for a week and need some advice on how to feed my frogs or if I need to while I am away. I have two 'Cobalt' D. tincs in a 20 gallon tank. They are about 11 months old now and I feed them every other day or every three days depending on if they eat all their flies. The tank is seeded with springtails as well. If I feed them a large amount of flies before I leave will the springtails be enough for them for a week? I have heard of people making small deli cups with media and a number of flies with small holes in the lid to make a slow feeder. What do you all do when you go away and have no one to feed your frogs while you are away?
