Yes. Of course the pairing process among the gobies can be pretty violent. If you are unlucky, it doesn't matter what size tank you've got. If you are lucky, you'll get two pairs from 5 gobies that start breeding in a 10 gallon tank. :roll: :wink: Seriously, give it a go: gobies are great community members and you should have plenty of space for them to pair up. Make sure there are lots of escape routes and hiding spots for harassed gobies to help them along.
