Descriptions and further reading
Family description (Grammatidae)

Basslets (Grammaer) are suitable for most aquaria, as they are a relatively easy and peaceful fish.
They are similar to Dottybacks (Pseudochromidae) in appearance and colour, but are more gentle and therefore a good alternative.

Basslets will always stay hidden if kept together with aggressive Wrasses, for example.
They like vertical rocks with many hiding spots, as it resembles their natural habitat. 

Several Basslets can be kept together, but not without risk. One must be ready to separate them, as they sometimes fight by locking jaws.
It can be an advantage to have different sized fish, as this increases the chance of having both males and females. They also require a spacious tank to be able to live together >65 gal (300 liters)
