Just a little update for you.
Yesterday I added a small frag of the Bubble coral I have in my big tank. It's not really a frag rather more a piece of flesh/skeleton that has dropped off the parent coral. In the past this has happened to both a Euphyllia
'Frogspawn' and a Caulastrea
coral that I have kept. Only the Euphyllia
babies went on to form new colonies though so this baby bubble coral may or may not survive to adulthood. I'll have to wait and see, it's just so perfectly Pico sized that I couldn't resist giving it a go no matter what the outcome.
Here it is looking a bit pooped out:
The other coral that I added came from the LFS. It's a small Fungia
sp. (or close relative anyway), not particularly colourful but I really like it anyhow. I actually went out looking for Zoanthids but they were either a boring brown colour too or the interesting ones were quite big colonies.
The hermit crabs are doing an absolutely sterling job on the tufty algae, there's just one small patch of it left now. Of course they've also eaten some new shoots of a rather decorative algae that was sprouting out of the rocks too but it's a small price to pay to get rid of the nuisance stuff.
Here's another close-up shot of my tiny 'shroom showing tufty-less rocks. You'll notice that the hermits haven't touched the Sargassum
algae, it must taste nasty or be too tough to consume.
Here's a new FTS so that you can play spot the corals.
Interestingly the population of pelagic copepods in this little tank has completely exploded without any predators to munch on them. I don't know where they go during the lights on period but at night there are hundreds out swarming in the water column. I have tried to take a picture so that you can all see too, the white streaks are not bubbles but lots of pods zooming about.
On the equipment side, I've had to rig up a small fan to blow into the hood as the addition of an extra light over the 'refugium' tipped the tank temperature to the hot side. It seems to be keeping the temperatures down but it doesn't bode well for summer, I may need to ventilate the hood a bit better for then.
