Unhappy My fish are dying...

2 orange von rio tetras, 2 guppies, 1 otocinclus, and a snail

So, I started this aquarium about 3 or 4 months ago. I finally got it to a point where nothing was dying and the water conditions were fine.

Recently one of my guppies was swimming oddly, I assumed it was swim bladder. After that poor little guy of my tetras started swimming funny.. he was pretty erratic at times or tilting to the side on the bottom of the tank. Any movement he made it seemed to take a lot of energy. Then, another guppy started acting strange, he was normally active but he seemed sluggish and he was staying away from other fish.

This morning I flushed the guppy. =/ and a few moments ago I was looking for my tetra and he was dead in a decoration..seems he had been for a little while and I hadn't seen him because maybe the other fish ate his fins..or they fell off.. who knows..

this is very stressful and sad.. HELP! =[

ps> testing my water tomorrow although I did test after the 1st guppy died and it was fine.

I'd test again. Temp, pH, nitrates, nitrites, ammonia, everything if you've got the kits. I'd also start doing water changes every day with Prime or another good dechlorinator just to make sure you're doing what you can for water quality issues all around.

The way it was one fish, then another, then another makes it sound like an infection of some kind. But I'm not really good on the fish triage. Hopefully someone else can suggest something there.

30g SE Asian Tank
15 Lambchop Rasbora
2 Gold White Cloud Minnows
3 Dwarf Chain Loaches
2 Powder Blue Dwarf Gourami

55g Amazon Tank
2 Wild Type Angels
1 Marble Angel
1 Black Angel
1 Koi Angel
2 Bolivian Rams
14 Pristella Tetra
10 Dwarf Pencilfish
2-3 Twig Catfish (to come)

It really is very important when attempting to diagnose a health issue to have all the background. Could you please post this info:

tank size
live plants or not?
water parameters: temperature, pH, hardness if you know it
ammonia, nitrite, nitrate--if you have/can test, what were/are the numbers?
frequency of water changes and amount of water changed
what water conditioner?
was anything (salt, chemicals, treatments...) added to the tank or is being added, other than water conditioner?
how did you cycle the tank, with these (now dead) fish or...?
how often were the fish fed, and with what sort of food?

All of this is significant because certain things have subsequent effects and can often suggest issues.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Right on Byron!! How much food?? How often?? What size tank?? Things happen a lot faster in a small aquarium.

When looking for a solution to an Aquarium problem go slow and change only one parameter at a time!
