Buying a 180G tank from a guy who has 3 others that are bigger. He breeds fresh water stingrays and is throwing one in for free.
My primary fish is the Arowana. How many can/should I keep in that size tank?
Possible tank mates (besides stingray):
~Lung Fish (I hear clean-up can be rough and I am not in love with them)
~King Tiger Pleco
~Fresh water Barracuda/Dog Characin OR Gar
~Green Terror
Any and all advice on the mix of fish that should be put in or additional options would be much appreciated. As stated, my focus is on the Arows, so I do not want to crowd the tank to the point it inhibits their growth
