Not sure what polys I'd do in the 100.
I can only think of delz and ornates.
2xThinbars and 2x red tail payaras sound good?
The 80 is probably gonna end up as a F0 labiatus breeding tank, and the 55 is getting lyonsi pair.
Cool.
I really Like red tails anyways, so one more cant hurt.
So..
3xRed Tails
2xdats (maybe. they grow slow for me aswell)
4xropes
1xdelhizi
1xornate
1xlap
