Can a fish out and out just not like a light?

This is interesting, Jay, because I'm seeing the same thing in my 55g. I just replaced the old no-name light fixture on my tank with the Aquasky from my old rice paddy tank. The old one had a definite pink cast to it, and the fish were very shy, constantly hiding out. I thought this was due to most of them being wild caught. Under the new light which is more of a normal day-light color, my barbs and danios are out and about all the time, though their colors aren't quite as vivid. It's interesting to see such a drastic behavior change just by changing the light.

On a side note, the aquasky is only 36", compared to the old light's 48", but it's just as bright, maybe even a little brighter. I ordered one of those hidden strip lights you suggested to illuminate the bank overhang in back, which should really make the tank pop.

Just don't expect the suction cups on the tube light to hold...

Actually I sort of thought that you would have already known that from previous posts on the light I got.

I considered several options as to mounting the light but decided to just keep it simple. Since the cups will hold for a few days I just put a little dab of silicone on the center of the cups; plenty of time for the silicone to set. In your case, if I understand what you want to do, you may not even really need to mount the thing; just put it where you want in the overhang.

Another thing I hope that you understand is that this light is not a strip. It is a sealed glass tube. It is not flexible.

Yep, I picked up on all of that in your former post. Thanks for clarifying, though. I'm going to mount it on the front, pointed toward the back.

And then there is this. These two cichlids used to be the worst of enemies but now they hang out together. I only see two possibilities.
1) Male and female and now mature enough to know it.
2) The old light was causing stress hence the hostility.

Personally I think it is the new light as it just seems to be too much of a coincidence that these two are now 'friends' and the rope is out and about so much now. Of course that does not mean that the male/female thing could not be a factor but I DO think that the light has a lot to do with it. Since they are the same species but the coloring is pretty different I'm guessing that they ARE a male and female although the one that is full broadside isn't actually not quite that light. There is a bit of camera flash effect such as the yellow/green dot pattern around the gills is actually blue. LOL! If you look about 3/4 of the way back on the broadside dorsal I guess I should clean the glass. And, no, there is no Ich. The white dot on the dorsal and tail are actually on the glass. Sort of funny what a camera brings out. I can't see the dried water drop or the white spots just looking at the tank. Then again the image is much larger than true life. On my 43 inch screen the broadside is ~10 inches but the fish is really ~2 inches max.. Sigh, here I go rambling again...

From SeriouslyFish…

“The male fish has 12-14 dorsal fin rays while the female has only 9-12. When in breeding condition the anal fin of the male swells and thickens.”

Again, thanks for that info. I finally got a decent photo and can only see 7-8 rays with the beastie somewhat stretched out but it would be easy to miss one or two due to the body being a bit bent. From the low number of rays that I can be sure of my guess is that Clyde is actually Claudette. Actually I just blew up a couple of images and keep coming up with 7 rays but that still doesn't mean that I may not be missing a couple...
