I say aro but that is because I am an aro fan also if possible you should get a red aro if possible.
Haha. Saves wateraba aba or lungfish.
probably the lungfish.
just think, if you have to break down the aquarium for a while, you'd be able to keep the fish in some mud in a bucket...
what kind of lungfish
G Aro..
If you get Aba Aba or Lungfish(most likely you're getting a African), they will need to be kept by themselves. African Lungfish and Aba Abas are known to kill their tankmates later on. There is only a few tanks that have Aba Aba/African Lungs kept with other fish sucessfully. I suggest keeping a Green Aro if your tank dimension is sufficient for one. Green Aros can be kept with other tankmates (depends on which one).
