megalodoras irwini

I'd keep a very close eye on ARTC and the irwini. It is not a question of if but when the ARTC will turn on the irwini and any other tank mates.

Max size tank rule of thumb: Minimum (!! meaning barely adequate) is 4xL by 2xL by ~2xL, where L is the expected max length. Hence, we are talking about 10'x5'x~4'. This is not 180 gal but 1500 US gallons. So don't kid yourselves that you can keep an adult irwini humanely (according to experts and professionals) in a 180 gal. It will be "only" ~10 times too small.

Having said that, 180 gal will last a long time, probably a few years, until the fish will start outgrowing it.

When considering this rule of thumb you should also take into account the behaviour of the fish. This is a relatively inactive bottom dwelling fish. My group of 9 hang around in one spot all day long, only moving when it's feeding time, or cruising around around lazily when the lights go out. I would also expect a max size of 24", not 30". Also this is a species thatusually only swims along the bottomso excess height is not likely to be used.

Personally I would feel comfortable with a 6' x 3' footprint as the minimum size for an adult in most circumstances.
 
I rather think 2' width would be ok since they normally don't grow bigger than that. Do you guys agree?
