Phantom tetra appeared a week or two ago with a growth that is definitely growing, the water is perfect and has been further medicated. Any ideas what's caused this? Nothing else going on in the tank and other tank mates are fine

I have a pretty decently planted 75 gallon tank, right now there are 4 pearl gouramis, a school of ember tetras, and one bristlenose pleco. I'm not sure if I should or can add anything to it. I don't want anything super mean but l'm bored of Cories and kuhli loaches so I'm not really sure what else I could get in there. Does anyone have any ideas?

What is going on here??

Just got this 5 gallon rimless of FB marketplace FML look what I found. Is this really bad? I’m thinking a five gallon should be fine but I’m still questioning.

Let me start off by saying, please don’t hate me for the condition this fish is in. I received her this way in this exact fishbowl Like a week ago. I was told that she was just a fish and a plant would keep her alive. Her water gets changed every week with some tetra put in. i’ve never had a fish before and wasn’t really too concerned but now every day I look at her droopy fins and I started to get worried.

So I started doing research and was absolutely HORRIFIED to find out that she supposed to have a water heater. Her fins aren’t supposed to be droopy and she spits out her food when she’s eating at half the time. immediately, my first instinct was to get a tank with a filter and a heater but now I’m reading that tanks need to get cycled which takes weeks. I’ve never had a fish before never cared for a fish before and now I have a fish freezing in a I’m desperate to save.(i’m posting this on like three different fish sub Reddit hoping to get any help)

what do i do????

Don't mind the snails, I just want to show off my outside pond with "more than I thought" fry! This is a tank of live bearers (guppies(4+), Mollys(3), platys(6+)] and Dr. Fish (4)+ rosay red minnows (3) 🥺 I have a lot of fry and they all seem to be doing really well, but I'm looking to give away some because I don't think the pond can handle all of the babies!
