Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I would wait until the Falco comes out of QT. If you add another fish now, you'll have to start the Falco's QT all over again as the angel may be bringing in something. Better to err on the side of caution.
The sell them that way because some folks just direct wire the ballast to the end caps and add their own power cord. They sell the assembled ones for folks that either aren't inclined to wire their own, or just don't want to be bothered by it.
I'm not sure if there is a way to open the case...
The one from Aquacave looks to be just the ballast. No housing, power cord or quick disconnect housing. You could always call them to clarify but that is how it appears to me. That would also explain the low price.
With nitrates of 30ppm doing a 50% water change is only going to bring them down to 15ppm as long has you have zero nitrates in the new water. Any trace of nitrates in the new water and the drop will be even less.
If you started with 30ppm and did a 10% water change your trates are only going...
It's hard to tell from the pic. Could be tunicates but The once I have seen were more rounded than spread out loke that.
Here's to hoping the glue and clamp work. Let me know and we'll come up with something else if need to.
That's not always true as sponges have intake syphons too. It looks like sponge to me. I have it in the 37 gallon in my room. They will come and go depending on the nutrient levels in the tank.
Well considering the tides changes can leave them exposed to the air for hours, remember a total tide change roughly 6 hours or so, you'll be fine with 20-30 minutes maybe even more.
I know some folks that ship their SPS corals wrapped in just a wet paper towel and they do just fine. That's...
A lot of times SPS are out of the water at low tide on the shallow reefs. I think you'd be fine for the short duration of a water change. There's a good chance they will slime up a bit as a means of keeping themselves from drying out.
I'd avoid the dragon wrasse, they don't call them rock moving wrasses for nothing. They will completely redecorate your tank. Not to mention the fact they get huge and nasty.
I believe what you are referring to as worms are actually vermetid snails. Those webs are how they catch their food.

Actually if you plan to do hyposalinity you want to drop them right into it not slowly lower the salinity. By slowly lowering the salinity you give the parasites a chance to adjust to it. Parasites can adjust to the lowered salinity just like a fish can. However the parasites can't handle the...
