I know they need 10 gallons each, and I know they have been kept in to small a tank while I was away ): I was not aware of the critter keeper situation as I was not home, which is why i thought it might be best just to get them out. I know 5 and a half is way too small but my thinking was is a clean and temporary 5 1/2 gallon tank not better than a filthy 1 gallon critter keeper? I was worried that is where they would end up again if I left them home in the 30 gallon. I was really at a loss for what to do. I really appreciate the advice from both of you, and will have to trust my family not to do that to them again. If they do, I will have to look for a new home for my frogs. );

right now they are in the largest tank I have, which they have been in since early december when I got home (30 gallons, will save up for the 20 long) and I guess I will have to leave them home in that and will try the sponge filter. I keep them at the proper temp and when I am caring for them their tank is always clean and comfortable with silk plants and hiding places. I will just have to trust my family to give them their food and clean them. And thanks for the info on the krill! I usually soak it until it is soft and then feed them small chunks, but if that is the wrong food I will cut that out ASAP. I feel terrible ): I really do try to do my best by the animals I care for, so I will try to explain what you said to my family and leave them at home. ps the pellet brand is zoo med aquatic frog food? is that an ok brand of food for them? It is the only kind of frog food we carry where I work. I was just panicking because I go back to school soon and didn't want them to be neglected so badly again, and the 5 1/2 gallon idea was a last resort thought. Thank you both for reminding me that my family should be able to manage as they really aren't complicated pets! and the sponge filter idea makes me feel much better. (I had been using a whisper filter for that tank.)
