Friday update - Tank's been wet for 90 days.
I have some very sad news to share. On returning to my office Monday, I was able to locate only one of the Clowns. After some searching, I found the other about 3 feet away on an office chair. At some point over the weekend it had jumped out of the tank, onto the desk and flopped several feet before ending up on the chair.
I struggled initially with the decision of whether or not to have fish in this tank having had none in the prior version. The shallow depth and open top would obviously be a risk but in 20 years of Reef Keeping, I'd never had a clown jump. After doing some research and talking with Tal (Clownfish Breeder) I decided to go ahead. This decision was also made based on the fact they would be the only fish in the tank and not subject to any harassment.
In observing these two for the past couple months, I saw no concerns - they rarely spooked and spent virtually all of their time along the substrate. They had seemingly settled in very nicely. I don't know what happened to cause the jump, perhaps the cleaning crew that works over the weekend spooked them somehow.
To make matters worse, the remaining Picasso now refused to eat. It's as if he was in mourning for his lost partner. I was faced with a decision. I had no other suitable tank to move the remaining Picasso into as my DT has a pair of much larger Darwins that would have made quick work of him. After talking with Tal, he suggested placing another Clown in the tank to hopefully "cheer" up my Picasso and encourage him to eat. As Tal had no other Picassos available, he volunteered a very new, tiny Percula (still developing it's stripe.) I drove a couple hours to get the little one and by 7pm Monday evening, my Picasso had a friend...by 8PM, they were both eating.
I'll ultimately look for another comparable Picasso, but in the interim, I'm just happy they're happy. All else is doing well, Corals continue to grow and envelop the acrylic. Water parameters are rock solid with no signs of algae.
I'll try and post a few photos later today.
