So weird. I haven’t been seeing them do it nearly as much. My fav white river cray will hang out up top, but usually it’s so I’ll feed her. She’s picky too... will grab things, nibble them, drop them and look at me like, “what else ya got?”
The behavior reminded me of fish when their water becomes oxygen-deprived, gasping at the surface because that’s where the gas exchange occurs so it’s more concentrated o2. Hanging onto the plants would make sense so they wouldn’t expend oxygen/energy. The behavior decreasing after adding/fixing equipment to boost surface agitation and oxygen seems to support my hypothesis.
If anything, the temp is a little warm for crays, I try to keep it at 80F, but the temp fluctuates since the tank is outside... sometimes gets up to mid 80s in the daytime. I’d say 79-83 is average temp.
with the plants floating at the top and the equipment/lining, I’m glad they don
