So we've noticed that some of our neon tetras have been getting very bloated and mis-shapen after feeding. One swims head down and swims aimlessly till his belly gets smaller. One swims alone in the corner. They just don't act normal, but then again, we've never owned neons before! My main concern though is that 3 of them have begun to lose coloration in the red band right at the end of the tail, before the fin.
So one of our swordtail is also concerning. The previously pregnant female was crashing around the tank, i thought ready to pop, and after she calmed down (no fry to be seen) I noticed this spot on her head. It's not fuzzy, its not an open sore looking thing, no mouth rot, fins look fine, just like some bad coloration. Shes acting normal otherwise. My girlfriend argues that there are darker striations running down her body that wern't previously there. I agree they wern't as red, but they look like normal fish coloring, like on a striped bass or something.
Of course I've read into NTD and have gotten all freaked out about it, but wanted to hit up the forum before dousing my tank with chemicals. That's my main concern, avoid chemicals unless I HAVE TO use them, my tank is all natural still, and I would like to keep it as natural as possible.
All the other fish have been acting normal other than the above. ONE other thing we have noticed though. The corys twitch OCCASIONALLY, like a singular twitch. My girlfriend says she has noticed them swim along the plants, which they never use to do. None of them are blatantly 'scratching against objects in the tank'. None of our other fish show any exterior signs of sickness/spots, like ich or anything like that. With the glass cats its easy to spot anything of the sort.
So thats whats going on... a bunch of random weird symptoms, which could be unrelated, but my fear is that it could be a parasite that they are all experiencing and I can't confirm it. Thanks for any help
side note: I added a second charcoal layer to my filter thinking that the twitch could be some excess toxins. the media are arranged: floss -> charcoal -> floss ->charcoal ->bio rings. Will it hurt having a second charcoal? There's no reason specifically why I might think theres toxins in the tank, I just did it as a precaution and since it was laying around unused. I also havent vacuumed the gravel in a while, going to do that this weekend, but what are the problems associated with neglecting the gravel vacuuming. Lengthy post, lol
