hmmmmaybe I'll go with a few tats w/ juvie pbass or something? but yeah that sounds good... I had heard the same about those particular motor's also.
If U plan to have P.bass pls target feed ur ray den..
The food probably wont hit the bottom..
I think its fine to house the tigirinus with the ray..
My rays are with a 16" tig and no probs at all..
