Aaron, I can always help you with finding the right pleco for you
I actually keep a pair of baryancistrus "gold nuggets" because they are largely carnivore and eat up any excess blood worms or massivore. They do a great job of eating up any left overs. You've got to be careful with these guys, though, because they are aggressive. Keep some driftwood in there for hiding spots. Dats are pretty tough and have handled them fine so far.
If you're willing to spend a little extra, L46 zebras are a nice choice too, as they are largely carnivore. Don't expect to see them out too often, though, as they like to hide.
I don't have too much experience with loaches, but Mike could attest to whether they do well with dats or not.
okok...i guess the last ones were a bit too big haha, btw what kind of bottom cleaners do you guys use? im at school most the time and travelling back and forth, so i might get some bottom cleaners to eat some uneaten food. im debating between clown loaches or some sort of catfish. stingrays are out of budget for now.
