Looking to Add another Fish to my 13.5 gallon tank

[ScottyD36]

I am looking for another fish to add to my 13.5 nano tank. Currently I have one clown fish and a red fin goby. I am trying to a find a fish that will fit into my tank while getting along with the Goby and Clown fish. I am not sure if having a thrid fish is just over load for my little tank or can be done. I plan on adding a pistol shrimp as well to pair with my Goby. Any suggestions or advice would be greatly appreciated.

Tailspin blenny. Cute, funny and will eat algae. Timid though so may be tricky to introduce last. Best of luck!

As above tailspot or twinspot, I have a twinspot in my Evo and it is a great little character and it eats algae.
