d0pey Posted July 14, 2015 Report Share Posted July 14, 2015 Is it me or do shrimp colors change when we turn the lights on? I notice all my shrimps look pale when the lights are off and I just turned them on. Within 1-2 minutes they return to their fully colored self.

Soothing Shrimp Posted July 14, 2015 Report Share Posted July 14, 2015 Crystals are knownfor this. In fact, when you get to the more pricy ones, the ones that keep their white in the dark are kept, while the ones that turn more transparent in the dark are culled. Some neos do, some don't.

Lyana Posted July 24, 2015 Report Share Posted July 24, 2015 haha, I was wondering this too. When the first first turn on in the morning my shrimp look a lot bluer then they fad throughout the day. So mine kind of do the opposite of yours. My prls on the other hand look horrible with the lights out glad it's normal Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted July 25, 2015 Report Share Posted July 25, 2015 Shrimp change colour according to the environment, lighting and the surrounding. This is for them to camouflage in the nature. This behaviour is the reason that drives dark coloured substrate was chosen as the standard substrate for shrimp keeping. It is normal for shrimp to colour-up when the lights is on. However, if your shrimp's colour fade away when the light is on, it means either your lighting intensity is too strong (they lessen their colour to blend in) or they are stressed. To find out if it is the latter, you just need to see whether they are active or not. If they are not active when lights on, then they are stressed.

Soothing Shrimp Posted July 25, 2015 Report Share Posted July 25, 2015 When the lights are on colors become more opaque to blend in and be camoflaged. If color is fading, light is not strong enough. Quote Link to comment Share on other sites More sharing options...
Lyana Posted August 1, 2015 Report Share Posted August 1, 2015 The lighting on my tank with the blue rilis is pretty weak Quote Link to comment Share on other sites More sharing options...
