He's the coolest thing I think I've ever put in one of my tanks. (Sorry Bongo Shrimp, you're super cool too...)

New addition:

Nice barnacle blenny. They are a definte for the 7.5g once it's up.

Yeah I saw him in his shell at the LFS and could not leave without him. So interesting. And tiny. No idea where he went today but I'm sure he's fine. Eats mysis like a champ.

yeah they are some of the coolest fish!

Cute! How about some updated pics of the rest of the tank? It has been almost a year ... =0)

Wow I didn't see this sorry. The tank is a macro'd up and is kinda boring other than all my sponge growing.

Look at this monster! I have to sell it cause it's too big and it deserves NOT to be chopped up.

I think I had that species of sponge, or very similar, have you IDed it?

Yeah it's Colospongia sp. Hard to get more exact than that. Most people give it high light and flow but mine grows like a vase under really stupidly old CF lights and minimal seahorse tank flow.

update?

I have not been adding stuff in here lately. Just growing tons and tons of my sponge. It got up to be 15" and I cut it back and its back to 13". Plus my other pieces are all over 6" or 7".

I have a giant peppermint shrimp in there which I am starting to suspect may be a different species than the average Lysmata wurdmani. Might even be a Klukenthal's Cleaner Shrimp cause he is huge.

I'm pondering an Orange Spot Filefish Pair.

Could use a trio of T.Tevegae, IMO.

Then again, I've never heard of orange spot file fish.

According to google, they look great but they munch Acropora all most exclusively . How would you plan to feed them? Train them on to frozen? As with most things on your threads, I'm intrigued.
