Thanks for the reply Dude! I'm hoping my arapaima will get red coloration, specially because of the fact that it´s farm raised and i´ve seen a lot of pale pimas from this kind of farms. As for the companion I ended up buying a RTC since I thought basically the same as you did, Arapaima grow stupidly fast, and there´s no way a RTC can catch up to that, I bought a RTC small enough for the arapaima to not be able to swallow him, I'm also planning on moderating it´s feeding since I'm really not that interested in owning a monster catfish so quickly, not with the arapaima.Hi Roberto
Your arapaima is still small mine started developing red at 12inches....And some arapaima will get more redder than others
As for tankmates... In my opinion arapaimas have the fastest growth rate...
Mine went from 12'' to 36'' in little less than a year... They do grow really fast
rtc should be okay when your arapaima is atleast 12'' +..make sure you get a small one but make sure he is not small enough to be swallowed by your pima...arapaima will grow faster than rtc
Yes! It's hard to believe but it's definitely bigger by the day! A biggger 250gal tank is now cycling so I hope I can move it soon.Certainly has grown a lot since you first post, good looking fish!
