crush my red devil

hey guys ok when i go by the tank crush (red devi) follows me and like when i sit down by the tank he like stands right in frunt of me not scared. but the kool part is when i close open my mouth it does the same thing i do i mean i know the breath but like if i keep it open for a wile he odes the same. its so kool if u guys know any more tricks i can teach him tell me. thanx

 

Both fish can get up to a foot long. Average i would say being 10 inches.
They both would need no less than 50 gallons each.

 

And that's just in terms of bioload. Due to their extremely aggressive nature, you'll probably need a lot more (like 180 for the pair) to provide them each with lots of territory and room to escape. Even that might not be enough, though. Most people can't keep any tankmates with RD's so you might be better off getting 2 50+ gallon tanks and separating them.
