I just put in 4 amano shrimp and did a 6 gallon water change in my planted 29g tank; suddenly, my horde of dalmatian mollies is incredibly jumpy. Whenever I get near the tank or something moves or changes, they all freak out and jump at the surface. It's a miracle none of them have jumped out yet. Does anybody know why this could happen so quickly and what I could do to remedy it? For now, I've turned off the lights and turned on the moonlights to hopefully make them see a bit less motion. The amano are pretty small, so I kind-of doubt it'd be that... didn't mix store water with my tank's water either, although they're from a healthy tank at a LFS.
Here are the specs on the tank:
29G, eco-complete & well planted, 3WPG 6500k light, DIY CO2
Last night's test results:
0 ppm ammonia
.25 ppm nitrites
20 ppm nitrates
4 dkH, 143.2ppm GH/KH
I'm worried that maybe something happened to our plumbing and there was something in the new bucket of water to scare them? :( They're mostly hanging out at the surface, jumping all over the place when one of them gets spooked (although the other species, like tetras & glass cats, are still in their normal spots acting calm...).
Thanks for any and all help.
