Blennies are usually on the small side (up to 3 inches) and sometimes a good candidate for a smaller tank. Don't keep them in multiples unless you have a larger tank and avoid keeping conspecifics in the same tank to avoid fighting over territory.

Make sure you have a good fitting hood to keep them from jumping to their demise. Don't introduce them to new tanks. They need lots of micro algae to graze on until you can get them eating standard aquarium foods. Try enticing them with thawed msysis, brine and herbivore blends.

Blennies

Ecsenius bicolor
Bicolor Blenny
The Bicolor Blenny is considered hardy but you still need to do a drip acclimation of about an hour or so, depending on the differences in source and tank water. Don't introduce them to new tanks without sufficient micro algae growth for them to graze on in between meals.

Salarias fasciatus
Lawnmower Blenny
This Lawnmower Blenny is quite endearing and has a very curious personality. They may remind you of an iguana or similar lizard the way they look at you with those orbital eyes. A healthy and well adapted specimen will be very aware of it's surroundings and observant of other fish and the aquarium keeper.

Ecsenius bicolor
Midas Blenny
This blenny gets to around 5 inches and needs at least a 30 gallon tank or larger. May fight with other blennies.
