Yeah, that's an Elysia sp. Sacoglossan Slug (A.K.A. a Lettuce "Nudibranch"), and it's an herbivore - if it's from the Atlantic, it's E. flava; if it's from the Pacific, it's E. obtusa@ISpeakForTheSeas nudi reef safe hare ?
Elysia flava or E. obtusa - harmless/beneficial Sacoglossan slugs. They're herbivores, with E. obtusa known to feed on Bryopsis, while E. Flava is thought to feed on Cladophora.
If you don't have access to their preferred feeds, you can try some of the below or another green algae, but no guarantees they'll feed on it/derive adequate nutrition from it:it seems at least some adults of some species can survive feeding on algae that isn't their preferred food, but juveniles cannot
Elysia slugs generally feed on siphonalean algae such as Caulerpa, Codium, Acetabularia, Halimeda, Udotea, Byropsis, and Valonia spp.

I like the stand.Welcome to our little build thread for this Alaskan 55 gallon tank! I'll be using this first post to house photos of tank stages, equipment listing, livestock & coral statuses, links, etc. In this thread we'll focus on the tank (our second 55 gal), with a slice of Alaskan scenery and shenanigans sprinkled throughout. Thanks for tagging along!

Hey All, well it's FINALLY time to get back into saltwater. This will be the wife and my second tank, we had to sell our first and only 55 gallon back in 2013 when moving to Alaska. We've traveled around this state a bit, and finally settled about an hour from one of the only saltwater stores that I know of in the state. Game on!!!
I enjoy any opportunity to get my tools out, so I'm building a custom stand. It's my second stand - first was for a freshwater 46 gal acrylic (still have it in storage). Since the new tank stand is almost completed, I figured it's a good time to get registered on the forum and start the build thread!
We will be using:
Custom Stand
55 Gallon Long Tank
BRS 4 Stage RODI
PSK-100H Skimmer
Radion XR15 Blue Lighting (x2)
Vortech MP10 QD Pumps (x2 or more if needed)
etc..
We'll be doing live rock with mostly coral, but some fish also - learned on the last tank to keep it simple with fish! Really hoping we can find a mated pistol shrimp and goby, that was our fav from tank #1! And of course there will be a few clown fish and anemones..
Stand progress, I love 2x4s. I'm no architect but if a single 2x4 can hold 1000 lbs vertically, 20 of 'em plus cross bracing should put me over 25,000(?) lbs. I think that will cover my needs lol:

Added a little trim and moulding, why not lol - just wingin' it here! :)

Great excuse to buy a new router for the doors :). Kreg Jig drilling used to secure the 1/3 pine, 5/8" brad nails for the 1/4" plywood backing:

That's where I'm at currently, finishing paint on the doors, hanging 'em, and bringing her inside. Looking to grab our live sand/rock next week and get this party started!
More to come!
