I ran a 12v to my bait tank but I think it's too much waterflow for a small bait tank, I had to turn the water outlet valve way down. I changed to a dedicated 6v battery for it, even then I'm still turning the outlet down but I've got all day use for both ff and bait tank, plus I can run 12v led lights now too if I want. I've been out 8 hours at a time and have not had any low battery power problems.

To answer your question, yes you can run 6v or 12v to your bait tank pump.
