Updated tank shots. Couple issues I’m having are the small patch of GHA on the top of one rock - it’s been a perpetual problem for years because my yellow tang won’t go that high in the water column. Every few months I scrub the 4” hair algae patch off with a tooth brush, but lately it’s been threatening to kill the acro frag in the middle of it (which also blocks urchins from squeezing in to the space) and since there really isn’t room for another acro colony up there anymore, I’m going to try moving the acro frag somewhere else, leaving the patch open for urchins to graze in, and see if that gets rid of the algae. And, I’m going to add fluconazole. Because if it does anything to weaken GHA it will help in the fight.
The other issue is two acros growing on the back wall tend to catch wads of algae in their branches. Again, my yellow tang won’t venture up there and urchins can’t reach/crabs can’t seem to scrabble up the smooth side of the tank to get into those colonies to remove the algae. I neglected to clear the algae long enough that the acro tissue underneath died and now the algae is anchored to the skeleton and not going anywhere. One of the drawbacks of acros on the back wall I guess.
In other updates, bubblebath unicorn has grown all the way under its perch and over many vermatid snails but still won’t sprout a single branch. On the other hand, Angry Birds is suddenly growing after hibernating for two years:
It still looks just blue and green though, so still not where I’d like it to be.
