Thanx in advance.

 

I'm partial to the Royal Gramma.

Saltwater Aquarium Fish for Marine Reef Aquariums: Royal Gramma Basslet

I've kept them in a 38 gallon, as well as a 20 gallon. Lasted for years without any problems.

 

sixline wrasses are cool, so are yellowheaded sleeper gobies, the sleeper goby will sift your sand for you too

 

The dragonets are cool - not sure how aggressive they are, but I don't think they are.

Saltwater Aquarium Fish for Marine Aquariums: Spotted Mandarin

 

they arent at all but they require a large amount of pods to survive in an aquarium, one of the most beautiful fish though IMO

 

pods? What do you mean?

 

copods. Usually need a refugium to give them a safe place to grow and multiply.

 

Just did a google search, and supposedly they are easy to culture in almost any aquatic condition.

 

yes this is true bu that kind of fish will wipe out a population very quickly, normally for een 1 you need a minumum of a 55 gallon tank, or with his it is possible with say a 10 gallon refugium, this just provides a safe haven in a sence for them to be able to multiply w.o getting eaten, and then the ones that go back into the tank from there become lunch lol.

 

but in all seriousness, a 6 line would make an awsome addition to the tank, i love the blue and the red stripes on them, i think thier awsome!
