Dragon gobies

patyouth711

a 55gal tank will be just fine for those fish. i have 2 dragons right now in a 30gal with a few other fish. the gobies CAN grow up to 2ft. my tanks ph is at about 7.0 right now and all my fish are loving it. just remember that the dragons are nocternal and love to hide.

also i've kept much larger fish in a 30gal tank so don't be worried about them out growing your tank.

good luck you've got some great fish!

As they are brackish fish, the exact salinity of the water shouldn't be crucial, as they have evolved to tolerate varying levels. I'd say the most important thing when it comes to salt, is not doing anything too quickly, and giving them time to adapt.

I've heard that if they are only kept in small groups the largest one will bully the others. Supposedly if you keep more than one, it's best to keep a larger group. The 55 may be sufficient for these guys for a while, but you should be prepared to rehome one or more of them if necessary. A 55 long would definitely be preferable. The larger the surface area, the better, as they are bottom dwellers. I'd worry more about bottom space than the actual gallons.

Sand is definitely a good idea since they will enjoy burrowing in it. They will cut themselves on sharp rocks and gravel. Light colored substrate will bleach them out more, whereas darker substrate will bring out their colors.

i know this is what you have heard and read but take it from someone who has them. i only have 2 and there is NO bullying at all. i have enough hiding spaces and to be honest one stays in its log and the other stays in its castle. and as far as them getting bleached out by light rock isn't totally true either. both my dragons have kept their beautiful oil like scales and my rocks are as white as can be.

as far as cutting themselves i haven't experienced anything like that so i can't comment on that but its def something to watch out for.
