I recently lost my favourite fish, a 12" jardini. I was growing him out in a 120 and about to move him to a 8X2X2 240g growout tank when I lost him. Now I have a brand new 240g sitting around and a desire to get back into aros. I know with jardini, tankmates are sketchy at best...especially another jardini. I'd like to know if I could grow out a nice Xback and red Asian arowana in this tank from 6-8" or so. I'd probably grow out a small group of red hook or black bar SDs as well in the tank as dithers. I know I'll need a bigger tank for the aros as adults. I'm planning on something bigger than my current cichla tank if I can grow out a nice enough pair. Thanks for any advice.
