I have a sea hare I am willing to lend. It ate all of the hair algae i had in my tank. My daughter has named it Fred. Fred if for loan only. If you kill Fred I expect you to replace him.
Nice gesture. They are very active and hard workers. To any potential borrowers, be mindful of where (and how strong) your powerheads are. Sea hares are very light and they can get sucked in pretty easily, mine was pulled in to an mp10 from about 4-5 inches away.
