I was doing a very very large water change by siphoning water out and pumping it in at the same time and just got done, my water is around 70° so it’s really cold especially for my tank and fish, there’s bubbles on the glass and plants which I think is from cold water and now my FH is moving a bit slowly and mostly staying still in an Anubias plant in the corner, my spotted Raphael was glass surfing a minute ago but went back to hiding and the foot of ny apple snails are kind of curled up sticking out of the shell, everything is still alive but I feel like I really messed up. Please help.
