I changed my mind on the aro selection, I'm going to get an RTGG and a black arowana, This way I wont be as worried about fighting!
The 180 is just a grow-out and they will be moved to a big tank (Most likely a 375g 96x36x36tall) and I will probably get a Leucistic GG and a Silver aro to go with the black and RTGG in the 375 when the day comes.
I cant wait! The tank will be set-up in the summer, I'll post plenty of pics!
