I love convict tangs!!!! I miss mine. Once I do a tank upgrade they will be back!Long time since a tried to upload a movie. Let’s see how it works now!

Me too! i still dream of a large school of convict tangs (or shoal? ;Bookworm) in the new reef tank. I got to test 8 together in the old bamboo shark tank, but they were not that interested in swimming together that often.. More chasing after each other.. So perhaps they are not the greatest schooling fish. Even if there are cool pictures of them schooling from the ocean. Or perhaps we needed more individuals in the group.I love convict tangs!!!!

My understanding is that fish will only shoal if they feel threatened since it is a defensive measure. They likely didn't view the bamboo shark as a threat.Me too! i still dream of a large school of convict tangs (or shoal? ;Bookworm) in the new reef tank.

How is the schedule proceeding? Still think you will have display tanks set up and running by early 2022?
Nothing special. Just going through pictures from the old Aquarium trying to find some inspiration. I miss having display tanks! ;Bucktooth
Yes, something like that. At the moment they do a layer of drainage. After that they will start the concrete work. Not the most exciting phase right nowHow is the schedule proceeding? Still think you will have display tanks set up and running by early 2022?
That’s true. When setting up a North Sea Kelp tank finding the right grazers can be hard. No tangs here.Woho, the requested coldwater images! Things just got real.
Looks like the regular tang method isn't working in this case. I have a hard time finding good grazers from our waters, so I have simply decided to keep the tank dark until I wish to view it. But as a public aquarium you do not have that luxury and need light so the inhabitants can be seen all day. Perhaps have a separate algae tank as a refugium? My limited experience is that kelp also has a hard time battling with hair algae. The conditions that favors the hair algae simply must go.
Yes, we've tried those urchin as well. They were really good at eating algae. Too good They chew off the stipes and holdfasts of the kelpHave You tried teh small "Tångborre"? (Psammechinus miliaris)
In the wild I have only seen it on brown algae where it did appear to feed on "aufwuchs".
That seems to be a Common issue with urchins all over the worldYes, we've tried those urchin as well. They were really good at eating algae. Too good They chew off the stipes and holdfasts of the kelp
Yes. The example with the sea urchins and disapearing otters we talked about at the University when I studied. It's a fine balance out in nature. And in our tanks sometimes. To much fishing on one species can lead to unexpected results, since we don't know all the interactions in the sea.That seems to be a Common issue with urchins all over the world

Urchin populations along the California coast have exploded during the last decade, threatening kelp forests and commercial fisheries. New solutions and experiments to address this are in the works.www.google.com
