Do they conflict with any other critters in the tank?
Are they potentialy harmful?
How many can you keep in a 90G tank?

Think they look awesome. Why wouldnt you want to add one, So your saying they love to get sucked into intakes, what about a 90 G tank with an overflow that flows into a sump below , will they be a problem with this type of setup?

That depends on the availability of the appropriate algae for them to eat. There are at least three species sold as lettuce slugs (they aren't nudibranchs) and they can be so hard to tell apart that it was only about a year ago that scientists realized two of them were different species. All of them are specialists on different algae and there is some dispute about which ones eat what.

They won't harm anything else in the tank, but wrasses, puffers, shrimp, and other critters that tend to nip inverts can be a problem as can overflows and intakes.

You can keep as many in the tank as you have the algae to support. That could be 0 or could be 10.
