Origami

All clownfish are born males. The dominant male in a group will become female in the absence of another female. This sex change is called sequential hermaphroditism and the change is irreversible. (That is, a female clownfish cannot transition back to being a male.) The female clownfish is generally the larger of the two in established pairs and the pair can become very territorial (as many damselfish are prone to be). In the absence of a female, a solo clownfish will tend to become a female. Thus, it's possible that the one remaining in your tank may be transitioning or has already transitioned. While it's possible that it's still male, you can't really tell. So the safe bet is to buy another, younger and smaller with the assumption that you're buying a male. It can take time for pairing to happen, but I've never had two that have not eventually paired up. Then again, I've only had a couple of clownfish pairs in the last 15 years since they can be pretty long-lived under the right conditions. So all this probably will haunt you the next time you're watching Finding Nemo. You see, when Marlin's mate, Coral, is eaten, Marlin (by all rights) should have transitioned to female and Nemo, his (her?) son, would have quite probably become Marlin's mate. But, that would have required more parent engagement with their kids than Disney would have wanted....

Well, I can't say that I've spent much time in the Monterey Bay area, but welcome! (Much of my youth was spent up and down the state, hence my curiosity.) Anyway, winter's coming. Be prepared and stay warm.

It's looking good!

Clownfish are very territorial. As juveniles, you can have multiple in a 125 gallon tank, but as they mature that tends to be difficult. My advice would be to pick another, smaller one of the same species and let nature take its course. And, sorry for your loss. I'm sure that a lot of us have come home to find that we've lost a jumper. I've had a few over the years. In one case, I actually got home in time to find one still alive and was able to get it back in the tank where it stayed for the rest of its days. BTW, I haven't had glass tops on my tanks in over 15 years now because I don't like the condensate and salt build up that cause light loss. If worried that way, I'm sure that you can probably find a mesh top that would keep jumpers in and still let light and moisture pass.

Welcome, Jon. From where in the Golden State are you coming from? Sent from my SM-N976V using Tapatalk

Cool. I've heard about Reef Notes but never picked up a copy. Sent from my SM-N976V using Tapatalk

Here. Picked up yet another book (autographed, of course) and checking the store out. Sent from my SM-N976V using Tapatalk

I've got a few books by Julian that I've accumulated over the years. Care to share what you have?

Also, keep in mind that many of those "desirables" are measured (above) in parts-per-billion and are a fraction of what you would like to see in your reef. For example, 705 ppb Magnesium is the same as 0.7 ppm out of the target zone around 1300 ppm in a reef aquarium. These additional components are largely not controlled by your local water authority (unless some start to exceed some water quality standard), so their concentration may vary over time. The purpose of using RO/DI in mixing your water is to start with a somewhat known baseline to which you can add your mix in order to maintain some consistency in the water that you use in your tank.

Thanks for donating. I did the same. And, yes, Windsor (his wife) is 2 months pregnant. It adds an added layer od sadness to his death. Sent from my SM-N976V using Tapatalk

Sorry. John's taking a pass. The species grows large and may be too aggressive for his situation. Sent from my SM-N976V using Tapatalk

Copps (John Coppolino) is WAMAS's speaker coordinator and highly regarded Marine Angel Fish expert. He's got several thousand gallons at home. Not sure about John's interest, but I'm tagging him as a potential party in the best interest of this specimen. Sent from my SM-N976V using Tapatalk

No details except what's been written about: Jake was on a flight itinerary to Bali and apparently died in flight. The last I read (yesterday), his remains were in Taiwan awaiting return. Sent from my SM-N976V using Tapatalk

OK. Reach out to me in a couple of days if you don't hear back or get status. Sent from my SM-N976V using Tapatalk

Trott, reach out to @Hilary by PM. She's coordinating with BRK.

I learned tonight that Julian Sprung (Founder of Two Little Fishies, long time reefer, and WAMAS Speaker) will be doing a meet-and-greet at Rick's Fish and Pet Supply in Frederick, MD on Sunday, October 30, from 12-5 PM. Julian has spoken to our club several times over the years and is a favorite at conferences, often drawing standing-room-only crowds. You'll be able to get special pricing on TLF products and have your books signed, too. Look for Rick to have things on sale, too, and maybe even a raffle. Mark your calendar if you'd like to drop in and meet Julian!

1 to 1.2 degrees, typically.

Circumstances are unclear at this time, but there's Facebook traffic from friends announcing that Reefbuilers pioneer, Jake Adams has died. Jake was a pioneer bridging internet media, reef hobby developments, and the growing commercial marketplace with hobbyists like you and me. He will be missed. RIP my friend.

Cool pics, Jessica!

Sorry, Milton! My last tank crash was about 11 years ago and occurred after a move. I won't get into details but, like you, I set off a chain reaction that claimed about 90% of my colonies and about 1/3 of my fish. Some were not quite the size of the one in your first picture and I had a couple that were about the size that Aaron (wildcrazyjoker81) posted above. It was heartbreaking to say the least. I can almost remember getting into the house (which we had bought but had not yet moved into because I was building out the basement) and being greeted by that funky ocean water smell. Coming around the corner and seeing the milky, cloudy water was a huge let down. It hurts, but you CAN come back. But you'll never forget that feeling.

Love it! Sent from my SM-N976V using Tapatalk
