I was actually going to suggest that, Catherine, but I'm not sure about keeping multiple gobies in such a small space? I have no experience with it, so it's all really speculation on my part.

I have a Six Line in my open-top, barebottom aquarium. He zips in and out of the rocks/corals and has a great ol' time. Or so it seems. No problems so far. And it's so cute, active and interactive.

Thanks Catherine and Drew. I thought a rainford goby needed a sand bed?

I don't totally remember. What I do know though is that they are small, and stay small, I don't think they grow any larger then 1" or 1.5".

Have you look at the nano fish list on some of the nano websites?

Yes, I was looking at a few different websites about nano fish. The problem I was having was that all the small fish that I really like either are known to jump out (BTW we are not using the canopy, the open top makes it easier to frag zoos) or they need a sand bed to eat from and/or sleep in. I'm pretty sure that a rainford goby eats by sifting through the sand for food. If one would be ok in a BB I would love to get one because they are a very cool looking fish.

I was thinking that a six line wrasse would be good to add. Then I remembered that we just added nudibranchs to our tank to help get rid of the aptasia, and I believe a six line would eat the nudi's right?

Not sure on that one. I've only ever had one lettuce nudibranch.

You could always try unconventional fish and inverts like say a ribbon eels or maybe even a frogfish. However, those two aren't compatible with your new little clown goby. Depending on how you are going to be doing the flow you could also look at seahorses and pipefish.

Rainfords/Hectors need sand, ribbon eels would escape,frogfish is a good choice for something different if your willing to feed it 3x a week, seahorse/pipefish will require a hitching post and low flow.

Thanks for all the ideas and advice everyone. We have a pipefish in our refugium, so we won't be getting another one. We thought about a frog fish but we don't know much about how to take care of one, so we got a yellow clown goby instead.

I think I'm going to get a red scooter blenny (lots of pods and live mysis in our system) and a black cap basslet (if I can find one) or (if I can't find one) maybe a royal gramma.

I went to the LFS today and I didn't know that black cap basslets cost so much! I couldn't find a red scooter blenny so...

After talking to the guy at the store (AI) he was fairly certain that the only thing that eats nudi's are powerheads so... a six line wrasse and a cute little bi-colour blenny followed me home :mrgreen:
