Blue Light with low Kelvin ???

[ivasawajin]

I have 2 toshiba LED+ 4 T5 flourscents each 80 on my 190 cm tank and the middle LED light is BLUE and i heard that fish like blue 1 hour or 1.5 hours in the morinin and 2 shours at night before the shut down , but my 2 blue LED light are SO bright it makes the DIsplay tank so bright i wont look like moon light , not even close , and i have a very cheap 100cm blue freshwater flourecsent with uknown Kelvins but when i turn this one on ( only this one ) the take will give moon light feel to it , but its a cheap blue light with no spiecial anything , so which one should i use in the morining and at night when my white T's are off???

I've never heard anything resembling that about fish liking blue light at certain times of day. I think someone was pulling your leg.

Me neither, but curious to hear more about this.

forget about the morning , what about at night after the 8-9 hours of light , i heard blue light makes it look like moon light and relive them from stress !

It can look very nice IMO with actinics on in the evening. It may do something for fish stress but I've never noticed anything.

Perhaps you're refering to the study of blue light reducing stress in a Nile River fish called Talapia?

The Nile? It's in Egypt. I did a little searching around on this subject and there isn't much out there on this topic that I could find other than a couple of studies done on a few types of freshwater fish. Mainly those that are kept for breeding and propogating purposes. I didn't find anything really claiming one thing or another in regaurds to blue light reducing stress in tropical fish. Not to say that no data exists...I just haven't found it yet if it does.
