Avocada Puffer

[Shovelman]

So ive got this bare 20 gallon tall tank and am wanting to try my hand at a different type of puffer. So would a single Auriglobus modestus (true freshwater species) be a happy specimen in a 20 tall that will be HEAVILY planted? I notice the 20 tall inst ideal as a 20 long would be but my stand wouldn't hold that long of a tank... As for food i have a 10 gallon as well that will be housing one of those self cloning crayfish that ive heard makes copies of itself like crazy along with snails in the tank so there would be lots of live food to watch this aggressive puffer munch on as well as frozen foods that will be trying to be fed as well. Basically my concern is it starting t pace the glass and become stressed, but i would think having the tank being extremely forested and jungle val completely covering 3 out of the 4 glass panes along with the driftwood and live food should keep him entertained and happy. If not please let me know! Any advice appreciated!(not a total new comer to puffers, ive had dp's successfully before and done rigorous research on almost all fw puffer species).
