Yeah, the tank looks great and I need to do another video update. I've been lazy LOL, plus, a lot of family health issues going on that aren't pleasant to deal with, so that's taken up a lot of my free time, but more, a lot of my energy, so when I have free time, I don't want to do anything.
Gracilaria is the chief macro now, and it's growing like crazy. I have another one, a green algae, maybe a type of hair algae but it grows a lot and very long and fast. And my sump has a ton of it now. I don't mind it because it looks pretty cool until there gets to be too much, and it's a nice color. I guess that it could be a macro. I haven't identified it yet. I'll get some close up pics of it. Anyway, the net result is that all of my cyano is gone, and algae doesn't grow much on the display tank glass, hardly at all unless I increase my photo period. Right now, my tank light is on 6 hours, and my sump/fuge light is on opposing 8 hours.
As far as aggression goes, I had a medium sized adult female blenny in my sump, and last week, moved her to the display. At first, all of the blennies picked on her for a day or two, now it's the normal pecking order and she's fine. Most of the aggression comes from the male blennies as they either chase the females out of their territory or try to court them in. This is normal behavior. The female to female aggression is minimal. I'd love to catch the other species of blenny this summer that lives in the Bay, called a feather blenny. I wouldn't mind a male/female pair. I'd also like to catch a small flounder like fish called a hogchoker, and another fish that I'd love to catch is a spotfin butterflyfish, a tropical stray that shows up in late summer every year. Also, there is a gorgonian type of coral, I think non-photosynthetic that lives in the Lower Bay, and I got a tip that it shows up in the summer along the beach, often alive, and I'd like to get more tunicates. I had a bunch when I started all of this, but haven't collected any since then. They don't live very long, but if I get the sea whip, then I will be feeding more often. It's all fun.
I saw some spawning activity, but some when my tank was warmer this past fall, mainly because the tank is much bigger and there are so many hiding places that the fish can do their thing without me seeing them. However, in December, I found a single baby mummichog killifish in my sump, so, I guess when my fish spawn, most of the babies become fish food for all of the hungry mouths! I moved the baby fish to my fuge and it's doing great, about an inch long now. Once it gets big enough, then it goes into my big tank. It's pretty cool. I had the same thing happen in my river tank, fish spawned and I had 9 babies, three are left that are big enough to not be food, which is pretty cool. I should have moved the 9 out, but at the time, I had no room for them.
BTW, at first I had my doubts about your seahorse ornament, but, now life is overtaking it, and it reminds me of Atlantis, and it's very cool looking. Very nice addition!
