Just a small update. No new tank shots yet, I still havent picked up a replacement rock to mount the loose xenia elongata to so things look a bit cluttered at the moment.
All this time and still no signs of predation at all, so I think I can safely conclude for good and all that removing that one rock from the tank rid me of whatever my problem hitchhiker was.
Most things continue to grow well. The cespitularia has surprised me by being a quick grower, more than doubling in size since I got it. It's spreading method of putting out club feet that attach to whatever they can land on and then sprouting stalks from it that creep along the rockwork is fascinating. It's currently making a beeline in it's growth towards several frags of the giant bali xenia so I may end up having to take some cuttings of it soon.
The sympodium continues to not do much. Not a coral that spreads quickly at all. Makes for a nice accent, but probably not something to devote a focal point to.
As far as the redspot cardinals, I'm down now to just the breeding pair. Unfortunate, but I won't add more of them as I'd expect this pair to harass them to death as they did the others. In a larger tank with a larger school of them I really don't think this would be an issue, but the
elos mini is definitely on the small side. Instead I'll add some trimma gobies when I get a chance, probably trimma cana.
From a technical side the tank is running beautifully. Feed the fish, refill the
ATO reservoir once a week or so, empty the skimmer and scrape a little bit of algae from the glass about that often... 5 gallon water change once a month. That's it.
