Hey all I've recently been finding alot of my shrimp have jumped the tank when previously they have been fine. I'm not too sure what the problem may be. This is also happening in my dwarf puffer tank around the same time. 20g long - 9 head n tail light tetras 8 diamond tetras 1 dwarf gourami ?? ghost shrimp (originally stocked with 30 or so, some berried) 5gal- 1 dwarf puffer 6-8ish ghost shrimp I've seen the tetras nip at the gs so I think that might be contributing but what I don't understand is why this is suddenly happening in both tanks at the same time.? The puffer normally doesn't bother the gs, mainly because they are much faster than him and he prefers to 'buzz' around slowly rather than chase them around. Some of the shrimp look cooked? Would that mean my heater is turned on too high or what? Normal temp is just around 80 degrees I will post the water parameters before I start my pwc later on today.
