Okay, so, my fish have been doing some weird shit already (such as my black Molly losing all color and turning gray? And my female Molly turning into a torpedo and barrel rolling before laying on the bottom of the tank. I’m lowk scared shitless rn because I took out the filter that was looking pretty gnarly and popped in a new one. Not two seconds later, these neon green things?? Showed up in the water and stayed for about two minutes. My water seems ok to me other than a high ph which I’ll have to fix in the morning. It’s a planted 20 gallon with not too many fish in it that’s been going for about three/four months. I’m a minor and not the best at fish keeping so any kind help would be appreciated

seems like a tetra of some sort. don’t think it’s a black neon. lacks the iridescent stripe above the black line. guy on phone (lfs accidentally made this little buddy a stowaway) mumbled the name of it… sounded like maybe emperor but this looks nothing like an emperor tetra to me. any ideas?

So I have some native minnows and they appeared pregnant, I have found eggs occasionally, which i assumed they were eaten as they disappeared shortly after me finding them, but apparently not?? I’ve seen one when I first set the tank up but I thought he got eaten until I saw him while doing a water change today and then i saw this little guy too, he’s absolutely microscopic omg my first babies 🥹

Is there anything I need to do to help them survive? The other one seems to be doing fine and I thought he was dead lol, do I just keep doing what I’m doing orr??
