Goby & Pistol Shrimp pairing

  • shrimp-goby-hdr

I got this paired up team at our club's last meeting. And they have stayed under the Acan colony in the 60g Anemone Cube. I took a few macro shots...

The shrimp is nearly blind, so the goby plays lookout. His tailfin touches the shrimp at all time, and with a single flick the shrimp retreats instantly, the fish quick to join in. It's a symbiotic relationship.

This is a Hi Fin Red Banded Goby.

Necessary shade

  • shade-diy-hdr

For many years, I've used foam sheets from Hobby Lobby (most hobby craft stores have these) to keep the refugium light off the rest of my gear. People often think they need colored or black acrylic in their sumps to avoid algae growth in other compartments and within their skimmer / reactors. However, that's really not the case. While we can see light in the other zones, what happens initially is the light bounces off the acrylic baffle and goes back into the refugium zone. 

And as the macro algae grows and fills the zone, even that is obscured.

2.5 years later (Day 915)

Today is the 2.5 year anniversary of the 400g reef 2.0, which is when all the livestock was re-added to the new 400g reef aquarium.  Originally I'd set up my reef in 2011, but after a leak occurred all livestock was moved out while the tank was replaced, and exactly 2.5 years ago I restarted again. Over time, everything has been growing, which you've been tracking via my blogs or youtube videos. 

Here's a couple of pictures from November 2013.

RBTA on the move

  • rbta-otm-header

If a bubble tip anemone moves, that can make a hobbyist nervous.  It could sting some corals, or get sucked into a pump's intake. In my anemone cube, that's nearly impossible.  Today's event was amusing because not only was the creature shifting to a potentially better spot, but the clownfish were going along for the ride. They were unwilling to accept the change, even though there are plenty of stationary bubble tips available throughout the tank.  Here are a series of pictures from this evening's meanderings.
