Blennies

Question
Which is better to keep, the Tail Spot Blenny or the Two Spot Bimaculatus Blenny?

Answer
Hi Peter,

In my opinion they both make nice additions. The Tail Spot Blenny having a color form consisting of Black, Blue, Orange and Yellow will add contrast to your aquarium.

Alternately if your aquarium is large enough, with plenty of rock-work, you could keep both species. They are generally peaceful towards con specifics, and may be added together at the same time, to help avoid bickering amongst each other.

I've included a fish compatibility chart, just as a reference for future use, from one of my favorite online aquarium stores:
