Blennies - Marine fish

Blennies - Marine fish are popular aquarium fish, and for good reason. They are peaceful, colorful, and many are downright helpful. For example, the aptly named Lawnmower Blenny will keep your green algae well trimmed and presentable. With the exception of Fang Blennies, Blennies are totally reef safe- in fact a reef environment is really best for them because they can be shy and the intricate rockwork of a reef provides ample hiding spaces. They are omnivores and should be fed a varied diet of frozen or live foods and plant matter. Blennies do not have teeth or functional jaw, so food must be small enough for them to swallow whole.
Blennies are often confused with Gobies, but there is an easy way to tell the difference. Gobies have two distinct dorsal fins, Blennies have a single dorsal fin that runs the length of their body. Also, Gobies' pelvic fins are fused to form a sucker, similar to Remoras.
