Swedish fish - behind the scenes rebuilding a public aquarium

[Sallstrom]

How do you guys determine how much to feed each system? I'd imagine it must be complicated having so many fish spread between all these separate tanks.

It's very non complicated
Before we go home, we put two cups in the refrigerator for the next day. One with frozen mysis and the other with frozen artemia. Together with some newly mixed saltwater.
Then we do two feedings a day, morning and afternoon, in all tanks with fish, or corals that eat mysis or artemia.
We all do the feedings, and I'm pretty sure they differ from person to person. So the fish doesn't get the exact same amount every day.
I don't rinse the food, some of my colleagues do, for example.
The amount in the cups has increased slowly over the last years. It's not that much I think, but enough for keeping our fish alive and well for more then ten years(in many cases). I haven't measured the amount of food we feed daily. 1/3 of a cup each, approximately.
Then there's other routines for the animals eating larger stuff like shrimps and mussels.

Sorry for a long answer.. ;Smuggrin

So your algae eaters only get what naturally grows in the tanks?

Yes, most of the time. We do have some green pellets and flakes if they start to look thin. But that's not often.
I want to feed them more home grown macroalgae, but they often leave some that ends up growing among the corals. Need to figure out a way around that.

I don't know why, but for some reason I figured you would have specialized blends for different species and make sure they were measured carefully.

You sound way too much like a hobbyist!

I love letting my tangs and other algae eaters graze. I should probably do it more. I may consider going to feeding Nori every other day. Especially with my tank as overgrown as it is currently. I haven't even checked to see if they will eat this newest algae I've cultivated. I've been pleased with the progress that the urchins are making but maybe the fish would give them some help!

We didn't feed anything in the 10000L tank the first two month. There were ten fat tangs in the tank at that time
Then you really could see their natural behaviour, and no begging for food. Loved it!

Yes - I did - but it was rather difficult in the snake pit of wires someone had create just above the lower ceiling

Time for a coral again. Here's a Porites lobata (that's my guess), the colony I had to use a wooden saw to get off a rock with unwanted stuff on it. It coming along very nice I think! Ten years ago Christmas tree worms were living in this colony, but they didn't survive. Would be fun to try those again.
This is one of the corals that were at the museum when I started working there

I get a kick out of how you think your is overgrown. I saw your latest FTS and it looked pretty darn good to me!

Beautiful and I would have loved to see it with the Christmas Tree Worms!

Another animal that has been at the museum longer than me is this Emperor angelfish. The photo is taken top down, the fish is on it's side checking out my phone. So it's pretty settled and hard to scare.
It had the juvenile colours many years, but changed to the adult colours when it was moved to another tank without any other angelfishes. I guess there were some picking order amongst the angelfishes in the first tank which made it stay as a juvenile.
This was my favourite reef fish when I was a child and I was lucky to see a couple when snorkelling in the Red Sea 1995. That was a so cool

He's probably as old as you. Like 29 yrs old. Right.

Beautiful fish! How is he adapting to his temporary system?

I'm curious, with the stress of all the moves into new systems, have you seen any signs of disease in any fish?

Thanks! It(I don't know the sex and trying to not call those animals he or she. Sounds better in Swedish perhaps ) does well. I saw it feed on small snails that sits just above the waterline yesterday. Most of the fish from those tanks started 2005-2006 are super calm, doesn't care that much about being moved. They had some ich in the old tank now and then, but haven't seen any now in the temporary tanks. We'll see, maybe we install a UV-C if it returns. Or ozone or H2O2.
We didn't have the same success with the Anthias and wrasse from the 10000L tank. I think they got too stressed from the move and half of them died

Exactly!!!

Sump music

When the fish and corals misbehave, not cooperating. Have the sound of a small boat coming toward them, people talking and diving into the water. Make them think , their coming to take them away. Heeee

It’s surströmming time. Sallstrom, you excited. I don't think I have stomach to smell it.
