JerSaint Posted November 14, 2013 Report Share Posted November 14, 2013 Hello Everyone, I was walking past my shrimp tank last night and my shrimp were swimming around like CRAZY! Is this some type of breeding behavior? Everyone seems cool this morning. Any ideas what was up? Quote Link to comment Share on other sites More sharing options...
ravensgate Posted November 14, 2013 Report Share Posted November 14, 2013 They do that typically right before or right after a saddled female has molted (but they aren't saddled all the time). Its males responding to a pheromone release. HOWEVER, they can also do that when a shrimp has a difficult molt...not stuck, just weak after a molt. I believe the weakened shrimp sends out some sort of distress signal....causes all the shrimp to go nuts and if the weakened gets caught they will generally get eaten. Generally when I watch this happen within about 15-20 minutes they go back to normal. If it's over a molted female who is 'ready' the swarming behavior can last hours.

Merth Posted November 14, 2013 Report Share Posted November 14, 2013 My blue velvets act like its a race. They basically swim/run laps around the tank. Quote Link to comment Share on other sites More sharing options...
OblongShrimp Posted November 14, 2013 Report Share Posted November 14, 2013 My crystals do it a lot too. They will start swimming around though to when I add food since they are trying to find it....I keep my shrimp hungry JerSaint 1 Quote Link to comment Share on other sites More sharing options...
