Female clown is not happy that her nem is upset over me putting my glass cover over the tank.

 

[r20crazy]

that is a showing of either dominance or submissive behavior(don't recall which) to the other clown... don't think has much to do with the cover

 

[GaryE]

She is quite a bit bigger... I'd say dominance.

If the glass cover isn't tinted, it shouldn't make a difference.

 

[GaryE]

Shouldn't, but the nem's tentacles were easily 3 inches long prior to putting the glass back in. He shriveled up to nothing within minutes of putting it in.

After I was done with the cover and removed it, he started extending them again. He's almost back to normal now.

 

[D-Nak]

Maybe the glass is blocking some of the UV, but the nem should get used to it. If you prefer to have the cover on the tank, just leave it on and the nem will adjust to the difference in spectrum or intensity.

 

[GaryE]

Yeah, haven't decided. Glass is such a pain in the butt to keep clean.

Brs did a video a while back and said glass covers can block a pretty good amount of light. Can’t remember exactly how much. I had glass covers and they used to get super gross and foggy. Ended up making my own out of this but in white. They sell it in 1/8” and 1/4” I got the 1/8” https://www.bulkreefsupply.com/1-4-black-netting-bulk-reef-supply.html

And also my clowns have done that before. They are still alive 2 years later

 

[GaryE]

I have a canopy on my tank, so screens wouldn't be ideal for me.

+1 on the female showing dominance and the male submissively twitching

 

[GaryE]

It's the female doing the twitching in this video, unless my female is somehow smaller.

 

[GaryE]

She's happy again...
