Its not the bass, its the turtle i'm worried about, but if it works, then go for it.Good call on the pacu. But the snakehead will be a NO GO in cali. But the other stock sounds good. For a 125gal, Orinos, intems, kelbs, would take a good while to grow out of. But a 125gal will be to small in the long run. But, yea, keep temp high, and add salt. You'll be good.
