Swimming Decorator crab

OK I have a theory and only a theory. As long as I have been keeping fish I am drawn to odd shaped fish like copperbands and long nose butterflies but I could never keep them as long as most other fish and looking back there were two causes for their deaths. One was jumping out. For some reason those types of fish like to jump. I lost about half of them from that. The rest of them died from something else. Last year I lost a copperband that got a bump and then a sore on it's side just before dying. ...

I built a few of these over the years and was not crazy about any of the designs but this one I made last month works 100%.
My reef now has a nitrate reading of 40 and I figured it would be a good time todesign a new Denitrification device but I had no idea it would work so good and so fast. They usually take a couple of months to fully work but I had it running for a month and I just tested it. Water going in has a nitrate reading of 40 and with just one pass through the device which takes ...

It seems that there are so many people in this hobby that are stressed every time they see something either growing or just appearing in their tanks.
I figured I would post things that over the years just went away with no help from me.
Hair algae.
I have no idea when I took this picture but it must have been at least 15 years ago. That fireclown is stil with me and he is almost 18 now, but look at all the hair algae. The fish and corals were in great shape, but the tank looked ...

I really hate the look of frags and up until a few weeks ago I never had any. It is not the frags I dislike, it is that silly looking round plug they come on. I personally never use them, but I like to glue corals right to pieces of rock, then as they age and get largter I glue those rocks to larger rocks to make them completely natural looking.
Now there are maybe 10 frags in my tank on those round plugs and when I get time I would like to break them off and stick them on rocks. They really ...

I have a yellow wrasse that doesn't look too well. I don't remember how old it is but I don't have it that long, maybe a year or two. I got it full grown.
For the last few months he is having trouble swimming. Wrasses don't swim well anyway but this one seems to have a tail that is semi paralized.
He looks good, eats and gets around but fish, like people also develop other diseases and maladies that we can't see on their skin. We usually see spots, discolorations, fungus, fin rot ...
