Lighting Acclimation Question and How High Will Clown Fish Jump?

[Jooak9]

Advice Question 1: Lighting Acclimation -

I have a new AI prime HD on a small tank.  Do I need to acclimate or is it ok to adjust the light to a par setting that is between 50 to 200 where my few LPS frags are at?

Advice Question 2: Clown Fish Jump Out Advice on Lid -

I was planning to have a glass top made with the center cut out.  My tank is a half circle shaped tank.

The edge of the glass top would have an approximate 3” ledge in the back overlap (straight part of the tank - tank back) And with an inch or so overlapping to go around the circular part of the tank.  The idea is to essentially make a ledge around the entire perimeter of the lid with an open center.

I have read clown fish don’t jump often, but if they do - it is generally to their demise!  So, how high can they jump?  I can make the lid up to a 1/2 inch thick and still have a partial open top with the center of the lid cut out.  (The thicker the glass does get more pricy though).

I currently have egg crate with a clear vinyl sheet glued underneath to help a little with the splash out and salt creep I was experiencing.  I’m worried the current set up with the egg crate and clear vinyl sheet may ultimately impact my par readings where I don’t have it consistent.  I also think the glass lid idea with a cut out perimeter and open center will be a better over all look.  However - could I possibly loose fish this way and/or if I make this glass thick enough / how high can these guys jump?!?

Ok - I appreciate any information you all have!

Appreciate the tips!

Clown can jump 6”-12” high. Most jumps occur from around the edges of aquarium.
Having at least a 3” wide lip all the way around should stop most fish jumps. 1/4” glass is plenty thick enough. Have them round all cut edges so it is safe to handle.

*most* is the key........fish have a funny way of finding any hole in your protection.

You didn't mention your old lighting......just try to match par.  But If your old system was not LED, then be really careful.

Thanks for all the info guys!

I had a top made with a cut out in the middle fabricated.  It’s not a 3” lip on all sides - partially because my tank is so small that it would have left for a small middle opening and partially, because I had it made before I read your post!  Hopefully this will keep them in.  I think my lip is 2.5” in the back and approximately 1” around the front curved edge.  It leaves about a max - 7” wide opening at the widest part of the curved front in the middle.  (If this is confusing - think of a full circle cut straight in half.... then take the half circle you have left and cut the middle out of it)!!

I’ll eventually post a video update so you guys can see what I’m talking about.  Hopefully this will be ok for the Clowns - which I just picked up some baby Picasso Clowns that are pretty cool looking!!  High hopes for these guys!!


At any rate - thanks for all of the advice everyone and talk to you all in the near future!
