A redtail will eat the oscars at some point (they grow much faster and get much bigger.) And won't fit in a 220 for very long. I'd say it will outgrow it in under a year, certainly can do that by the one year mark.

A 220 is also small for an aro long term, although it might work for more than a year. I know people will keep an aro in a tank that size a bit longer, but it wouldn't be my preference and imo at some point it shouldn't be in something that size.

A smaller catfish incapable of or unwilling to try swallowing a 12-14 inch fish is what you might want to look at if the catfish is a quick grower. For example, a megalodoras uranoscopus (irwini) can get to a max of 20-24" (although typically smaller) in a tank and won't try to eat or kill the others.


Then look to upgrade the tank or move those fish in 12-18 months, although sooner might be good.
