tire track eels

Question
we recently sold our fish and are keeping our tire track eels.instead of us keeping them in the 55 gallon. we want to put them in the 20 gallon as we are in the process of moving, but we do not have air bubbles in the tank.....do the eels need air in there water? thanks

Answer
Sasha,
   your aquarium will exchange O2 at the surface without any airbubbles.
how many tire tracks are you putting in the 20? how big? If you have a dozen you
may want to add some additional filtration.
If its a couple/few and they are average sized, don;t worry about it...
just keep the tank covered as they love to jump!..
enjoy your aquarium.
