which blennies/gobies for 20 gallon long

I've been looking at my fish options and I'm pretty limited with a 20 gallon long. I've been considering the following to go along with my pair of Darwin clowns:

2-3 Barnacle blennies
1 black sailfin blenny (would be good for algae control)
1 tailspot blenny
1 twinspot goby (good for cleaning up the sand and eating food at the bottom)

Of those options (or other suggestions), which would you choose and why?

The less effect on the bioload the better as well, as I'd like to get as many fish as I could in a 20 gallon.

Thanks.
 
I would say the tailspot blenny would be a great choice. It stays small and your tank is pretty small. It eats prepared foods and so you won't have a problem feeding it. One can't say the same for some of the other choices on the list, especially the twin spot goby. Also, they are incredibly cute and very colorful.

i have a little colony of 6 barnacle blennies (A. balonorum) and they're pretty fun to watch at feeding time (they look like "whack a moles"). they were hilarious when i first added them, as they all had to try out all the holes in the LR and shells. however, once they settle in, it's all about the food.

you also might consider a small waspfish or scorp...a 20L is perfect for many species:

I've never heard of a waspfish. Is that picture of a baby scorpion fish? That looks awesome. Those are poisonous and non reef safe tho right? Where an I find more info on these guys?

Sorry I should've specified that my tank is a mixed reef with mainly LPS and ricordeas with a pair of darwin clown fish. Are they ok in such an environment?

I've heard that the twinspots can sometimes become aggressive and nip at coral. Have you had any problems with yours? Do you think a twinspota nd a midas would get along?
 
My twinspot and midas blenny get along fine. I think they are both wonderful fish. Neither of mine are over aggressive, but they don't allow others to bully them.
