You're going to have a hard time adding anything to that tank with those two fish. I would not suggest the tailspot blenny for that reason - they're pretty timid little fish. A good-sized starry blenny might work.
If you're looking for a fish to control an algae problem, I don't think you're going to find one for a tank that small. Try some turbo snails. And up your water changes.
I am looking for a small herbivore fish for my 29g. Right now I have two small false percs and a bangai cardinal. The algae isn't hair algae, but some sort of the followings from pictures I've seen:
caulerpa-taxifolia
bryopsis-pennata
Caulerpa-sertularoides
I was looking to add a small Yellow tang for now and then give it to a friend after a while but feel bad doing that. I also saw a coral beauty angelfish. Would that work?
Probably not. Even ignore the tank size.
totally. adding a yellow tang (no matter how small) to a 29g is a really bad idea. 29 gallon is too small even for a juvenile yellow tang and it will sure be under stress.
