wow i thought that was an octopus at first!I custom built this 90g tank is 36" x 30" x 20" and was built in December of 2019. It's just starting to look good.
This photo is from back when I was just getting the tanks started, early in 2020. The tank in the center is just a short term 'holding tank' for wild collected livestock.
This is my new (Feb 2020) 16g RFA breeding tank. It has a HOB filter with 2 sponges and a layer of filter sock in between as well as a Tunze in-tank skimmer. That's it! And I've had several RFA spawning events already.
And just in the last couple of weeks I've had these serpent stars climbing all over each other under a rock near the front of the tank where I can watch. A brittle star often joins in the party. They seem to all be OK and they do take a break and come out to eat!
