Today I noticed one of my neon tetras was behaving a bit odd, and when I looked at him up close he had white spots all over his body. Is this ich? I live in the EU, what products can I use to treat it that are available to me? Should I treat the whole tank?

This fish lives with 9 other neon tetras, 10 Pseudomugil luminatus, 10 Inpaichthys kerri "Superblue", 8 kuhli loaches, 3 blue neon gobies, 3 pearl gouramis, +20 neocaridina shrimp, 7 pinocchio shrimp and 1 blue jelly snail. They live in a 200l heavily planted tank at 24ºC, 7.3pH, 0 ammonia, 0 nitrites and 15 nitrates. The tank has been set up since November and I started adding fish 1.5 months later. There is a small cyanobacteria problem that we're treating with Easy-Life BLU1000 Blue Exit, but we just returned from a 3 week long holiday and the tank was in my parent's care, and it was covered in cyano. We cleaned it all immediately and started treatment but I assume it must have been stressful for the animals.

Thank you for your help.

Hi all! Currently managing a 10 gallon community tank (pictured first) and building a 2.5 gallon shrimp tank.

The ten gallon features the following Aquatic plants - Eleocharis acicularis, Hellanthium tenellum 'Green', Dwarf Water Onion, and a Water Banana Plant (Nymphoides aquatica), with plans to add a floating Java Moss ring and a Java Fern. I was wondering if you have any other plant recommendations for the tank. The tank houses Ghost Shrimp, a school of Ember tetras, and some Pygmy Corydoras. It also has a ceramic shrimp hideout, silk leaves for pygmys and shrimp to rest on, and a Eucalyptus root. (with an adjustable heater and HOB sponge filter.

Also working on making a 2.5 gallon for neocaridina (Blue Dream or Jade Green, not sure yet). All it has for now is a Java Fern and a mini air pressure powered sponge filter; I want to add some Java Moss and some Marimo Moss Balls. Looking for recommendations here too!!

Let me know if you have any plant recommendations for either of these! Preferably unique/underrated ones.

My fish has been doing circles on his reflection for most of the day. Is he playing with his reflection? He's aggressive even to other Buenos Aires tetras and I had to move him to out of my 29 gallon tank to a 3 gallon tank a couple weeks ago. He's in there with a few corys and that's it. I don't think he's very happy about it but he was terrorizing my other tetras and barbs.

Okay so I keep a 10 gallon community tank and I noticed one of my black neons was sitting at the surface of the tank gasping for air. It was dinner time so I fed as usual and put some flakes next to it but it ignored the food. It’s so out of it. I was able to scoop it up in my hand to move to a container and it barely reacted. I checked my water parameters and it was 0 ammonia 0 nitrites and 0 nitrates (my tanks are established and always read 0,0,0) temp is 75-78° F. None of the other fish are gasping and are acting completely fine. Can someone help? I would prefer not to lose this baby!

Hello, I've had this fish for probably a month now and hes always had a slight wonk on his side but was always swimming fine so figured he was just deformed.

I went away for a week and came back and today noticed hes swimming upside down and struggling to move around.

I'm not sure what this is, all of my other tetras are fine so I don't think it's spreadable.

Does anyone have any idea if this is dropsy or bloat or something else?

Ive posted this on multiple places and i keep not getting a single answer and my fish are actively dying one after another, my fish look very sick and some are insanely bloated and some are very thin so im assuming dropsy for some and from what i know they need a epsom salt bath but i dont know how much epsom salt + water is right and i dont wanna go off of what the ai thing on google tells me, any help is appreciated

Please ignore how dirty my tank looks i was gone for a few days and had the lights on (they were still fed daily)

Last night I noticed these white spots on my Bleeding Heart Tetras (tank mates are a clown pleco and Gold Inca Snail). I think it’s the Ich or White Spot Disease but will be my first time dealing with this so wanted consensus. And then as far as treatment, I know I should increase the tank temperature, do daily water changes and I got API’s Liquid Super Ick Cure for delivery today to start treating them tonight. Any other recommendations?

My water parameters were good but this is a new tank set up (have had these guys almost two weeks).

Thanks in advance!

Just noticed this fish has light coloration on top and bottom, I’m not sure what it is, anyone able to identify what’s going on with him/her?

I am a beginner with a freshwater 20 gallon planted tank. It has 6 corydoras, 4 shrimp, and 2 snails. I recently brought home 5 von rio flame tetras. Yesterday, I woke up and one of them was nipped at so badly it didn’t have any fins or eyes. This morning I wake up and one of my shrimp is split down the middle and eaten and ANOTHER tetra is nipped badly. I was supposed to have a betta community tank but I’m scared to purchase a betta with these in my tank. I don’t know what to do. Do I take them back to my LFS? It’s making me so sad :/. They are extremely aggressive and honestly I’m afraid they’re going to attack my corydoras.

Store said they were neon tetras but like they don’t really look like neon tetras. They were babies when I got them and looked like neon tetras as babies but they look like this now? Any idea what they are

For context, I've got two aquariums and in one I have ember tetras. I was trying to culture copepods is a small bottle I guess and I was gonna give up on the project a few days after I started it and I moved the moss (that I had previously moved from my two aquariums) and noticed this small guy, now I have gotten insect eggs in my big aquarium before and at first glance I didn't even know if it was alive but when I nudged it with my pipet and the shit darted I confirmed it was indeed alive also resembled guppy fry which I have seen before so I searched up ember tetra fry and I definitely see a strong reassemblance

Now I wanna know whether it's an ember tetra fry because there should be more than one or if it's just some fly larve, I don't t wanna get my hopes up even if it is a baby tetra because it probably won't make it in my unprepared hands but I just wanna confirm my suspicion

I have neon tetras in my 240L tank with a fluval 305 filter.
For some time there has been a slow growing white patches on its scales.

I used my 10L quarantine tank with esha 2000 which has not helped.

How much salt do I use per 10L for the neon tetra
I am planning to do it for a day but idk how much salt to use. ChatGPT,Google and other websites have different advice.

I recently noticed this particular male ember tetra starting to lose some of its colors, and its belly is also a bit sunken even though it's eating and being very active. My suspicion is that it has contracted callamanus worms, as I had problems with callamanus worms in another guppy tank I have, and I believe it somehow got into this aquarium. I didn't see any red worms coming out of it (typical of an advanced stage of callamanus worms), but I believe it's possibly because it's in the initial stage of a possible worm infestation. I couldn't see its poop to analyze if it's healthy or transparent, so I'm not sure. I'll post some pictures of it in comparison with the other ember tetras that are healthy and haven't shown signs of disease yet. In any case, I applied a dose of 3mg/L of Ripercol (active ingredient levadamisole) to paralyze and expel any possible worms from the fish. Unfortunately, I had to use it on the entire aquarium even though I have ramshorn snails, which could probably kill some of them since I was told levamisole affects invertebrates. Anyway, I came here to seek guidance or tips from someone who has gone through something similar.

Note that the parameters are 82-84 degrees Fahrenheit / 28-29 degrees Celsius. Regarding the pH, this is probably a point of concern. I've been using DIY CO2 with sugar and yeast, and I don't remove the diffuser overnight. I believe this causes a pH fluctuation. I don't know if this possible fluctuation could have affected the fish or lowered its immunity, but with my tests i saw that the fluctuation isn't huge, about 6.8 ph during the day and 7-7.2 at night
