that should be fine. get a low profile sponge filter. then fill it up to just above the gars back. just enought to make sure it is not exposed. just make sure it is above the sponge filter by about an inch. if that means it is a few inches above the gar then that is what it is. that would be the only way to filter it with out trying to make a sump system with an ajustable overflow tube. if you hae a spare sump or even on top of your current disply. drill into the side neer the bottom of the tank you get. then on the other side of the bulkhead place a pvc 90 going into a streight pipe. cut that pipe to the hight to give you the right depth for the gar to be covered. then on the other side have it drain into your main tank. use a powerhead or a low flow pump to pump from the main tank into the temp gar er. those are the simplest ways to get what you need. the problem with the sponge is new it will not be cycled, the above tank overflow system will allow the gar to remain in the system.
