Dragon gobies

[My Head Hurts]

Hey, ive had my eye on a dragon goby for some time. ive read they're predators but had lots of people tell me they're pretty harmless. Can anyone tell me from experience please!
Also, are they any special keeping needs?
Cheers

The largest fish a dragon goby can predatate on are fry, they are actually filter feeder that feed in much the same way as whales do by straining water through their gills to collect tiny micro organisms.

When buying a dragon goby you must be careful which one you buy, many of the ones sold in lfs's are Gobioides broussonettii which is a brackish fish and will not live long in freshwater, the freshwater species is Gobioides peruanus which can be identified by its lack of vertiacl dark bands.
