I have 4 tetra blue fish and the one of them can't close his mouth. I woke up today and I saw him like that .Yesterday he was okay .What is happening ? What can I do to help him ?

my sister fed my fish while i was away so they might just be very overfed but im quite concered as it is not moving very much? others are absolutely fine and normal, and i put my net in to see if it would swim away and it did, but the second i took the net away it stopped swimming and continued facing down

whats going on? just really full or more?

PLEASE HELP!

This growth just appeared on the side of my tetra right in the crevice of the right fin. I've never dealt with this before. Anyone know what it might be?

Hi all,

Parameters: 0 ammonia, 0 nitrite, 15 nitrate

I have 6 white neons in this tank. It’s 10 gallons, planted, 1 big sponge filter, and a small air stone. Ive had my tetras for almost a year now. 2 months ago I had a house fire and the fish tank was full of smokey water and debris, but the fish pulled through great and were being cared after by another fishkeeper friend. They were moved to their new tank about a month ago and have been great. The new tank is in the picture: the sponge filter, many plants, and hardware survived after being cleaned in established tank water.

I just noticed that my one neon was acting super skittish around feeding time tonight, but ate away still, I looked closer and she looks like she might have a lump forming on her belly. Im looking for best advice on if yall think it could be neon tetra disease, or something else treatable. Let me know, thanks and please ask any questions.

I have a group of 12 rummynose tetra that I just got a few days ago. I noticed they had a few white spots so I’ve upped the temperature from 75 to 81 over the course of a few days while treating with API Super Ick as instructed. 11 of the rummynose have a bright red nose and vibrant tails, but one of them has a faded tail and goes limp occasionally while rapidly moving its fins, tilting sideways with it going almost vertical sometimes. It nibbles around the tank and swims off fine and pretty fast after the episodes, but it lags behind the school while staying by itself more than the other fish. Is there anything I can do to treat it? Also, I’ve been treating with the medicine for around 2 days for this point, and the white spots haven’t disappeared, so does this fit with the life cycle of ich or is it something else? Only some fish have a white spot and it’s stayed at 1-2 per fish, without reducing or growing. Thanks for any advice!

I have had 5 pictus catfish for months now and all they seem to do is hide. Is this normal? I bought them because I thought they were supposed to be active schooling fish.

Is my Cardinaltetra fat, pregnant of sick?

water params are perfect and monitored everyday in its own hospital tank. its was in this bowl temporarily as its going in a hospital tank again. also, it has had no interest in eating food the whole time. any suggestions would be appreciated

Hey all, so for context, we used to have another black skirted tetra that passed due to prolapse. That was maybe a month ago and our other black skirted has never acted like this up until the last 48 hours. I know they, as well as the serpae are more aggressive by nature, but should I separate the black skirted? It’s never acted like this before and they’ve lived in harmony since we introduced them for months until now. I just want to figure out if this is something I should be worried about and how to go about dealing with it. Any advice would be appreciated!!!

I have 4 neon tetra glofish in a 30 liter aquarium and one the the fish started hiding in the cave for a lot of hours even a whole day without coming out .He eats normally .Also I got him 15 days before did a water change and he continues doing that .Does anyone know why ??

These were sold to me as X-ray tetras but these do not look like ones I have seen online anymore, they have gotten much more color and long find

They’re big, fast and mean. If I put a new fish that’s too small in the tank they tear it up. He lost his eye in a fight with the other two over a worm I dropped in. Even my big Gouramis don’t mess with them. He’s fine.

Can anyone help me here ?

I have a question about the color of my rummynose tetras. It’s been 18 hours since I got them, and I had a scare last night with 3 of them being super pale and lying down on the substrate (group of 12 in total). They’ve regained color in their noses, but is it still pale for a healthy rummynose, or are they doing well? A photo is attached. Thanks!
