Two clowfish jumped after adding Macroalgae

[Nstocks]

I have a 80L aquarium set up for 6 months or so, with two health common clownfish.

This week I added three small clumps of macro algae; red ribbon, Caulpera Prolifera and Hailemeda. The Macroalgae was in a separate tank for 24 hours, after which I swished it around and did a few rinses in saltwater before adding it to the tank.

Within 24 hours, one of my healthy clownfish jumped out a small gap overnight. I covered the gaps.

24 hours again, the second clownfish jumped out, again at night through a different and smaller gap.

No other changes were made in a month other than the macro algae. A month prior I added a tailspot blenny which underwent 30 days of copper power, the same as the clownfish.

What gives!

I replaced the first jumping clownfish yesterday by purchasing a new C. Clown to a QT tank... Guess I'm out shopping again this weekend to add another clown to the QT>

A couple of months ago I also discovered that Clowns are jumpers. Not something I'd ever heard about them before. Fortunately I noticed he was missing quickly and he survived the fall. I'm sorry yours didn't.

I don't think its the macro algae, I think its just coincidence. I have 4 tanks without lids, I haven't had lids in 20 years and my fish don't jump. I'm a very firm believer that if fish are jumping, they are not happy or there is something in the tank they want to get away from.

I agree that I think it was just a coincidence
