Fish mysteriously dying.

I've had about 4 fish die within the last month or so and I dont have any affordable fish stores in my area to buy testing strips or anything. It all seemed to start when I added a new plant in the water. Water sprite i believe it was. It ended up dying. I have 2 pieces of medium/large driftwood in there as well, so the water does have tannins.. and i read that can lower the PH? I have a pregnant fish in this tank right now and Im worried that she and her fry will die so please reply asap... Its a 30 gal aquarium and I have 7 swimmers, 1 pleco and 1 catfish so I dont see it being ammonia poisoning. Please help!

If it all started with the new plant I'd suspect bacterial or viral infection, assuming the new plant was grown in a tank with fish. What symptoms were the dead fish showing?

When I finally purchase plants for my tanks, I'm planning to sterilize them using potassium permanganate. I've read it can be done with bleach as well.

I'm sorry you're having trouble. It's incredibly frustrating not knowing what to do to solve an issue.

Im not sure that there were many symptoms. The first fish that died was breathing very heavily and quick, and his gills looked to expand pretty big when he breathed. The next two that died didnt show any of the same symptoms, i was suprised when i found them dead. Most of them seem fine and then I wake up and they are dead. My last one that died seemed to get swim bladder after she ate, so she was a little wobbly the night she died but i assumed it was from the swim bladder. Im worrying because now my pregnant fish is kind of swimming funny as well, face down into the bubbles and making sharp turns away from bubbles, only to go back to the bubbles for a few seconds.

It sounds like they're not getting enough oxygen. Do a good water change and increase the amount of air in your tank, either with an air stone or increasing the flow rate of your filter. I'm no expert by any means but if they're staying where the oxygen concentration is higher, that would be my first thought. If they picked up worms or disease from the plant that attack gills and makes it harder for them to exchange ammonia for oxygen, they'd do the same thing.

Best bet is a water change, increase the air flow and maybe use some aquarium salt (not table salt) to help their gills? When my fish were sickly I used 1 tbsp of aquarium salt for each 4 gallons of water. Please do not use table salt--that will not turn out well.

Once again, I'm guessing based on what I've experienced and read.

If you can, go online and purchase a good liquid test kit. Having that information is important when things go wrong.

That was my initial thought too, but my tank is 29 gal and i have a 30 gal filter and a 40 gal aqueon (i believe) air pump and about a 6" air stone so there is a good flow and air. I did a water change yesterday, almost 50% and everyone is fine for now. I did notice though while I was doing the water change that the water is a lot dirtier than i would like. Also the water is yellow from tanins, but as I was doing the water change I realized how much debris is floating around... even if you look at the tank now you can see little pieces of filter dirt or something flying around. I have a topfin filter, so it has the carbon film and theres this green plastic thing that helps stop debris from going around, so i heard you arent supposed to do a big water change and clean filter the same day, you should wait a week, so i took out the green piece instead and cleaned that. The filter also has an overflow spot so that you know when to clean it, and it isnt overflowing into the side so i dont yet need to clean it. There isnt a lot of debris now, its mostly bubbles that you can see, and i will attach photos for you.

Im not sure if this matters or not but I do have one plant, a petite anubias, which is fish lined to one of my driftwoods. I've had it there for about a month and a half i would guess, so im also wondering when i would be able to take the line off? I also bought this plant fertilizer stuff, and it says for 30 gals to use about 3 squirts per week and water change every 2 weeks. I only put about one pump per 2 weeks or so since I only have that one plant. That shouldnt be causing the deaths should it?

The first photo is of my ram, who is healthy looking, as are all of my other fish. The second is to show that the bubbles reach everywhere at the top, and then the filter pushes them down to circulate it more, as you can see the bubbles in the background of the next photo. The fourth photo is of the filter and the bubbles the filter pushes. The next is of my entire tank just in case that would help? Then the next is of my healthy looking angelfish, and you can see the bubbles and circulation. Then theres my pregnant molly who is playing in the bubbles. Im not sure if shes just playing or if she actually needs the bubbles. She doesnt always do it, but once she starts she doesnt stop for a while. I took that photo about 30 mins ago and she is still doing it on and off. she will go over and do whatever with the other fish and then she will go and dive and then swim away and come right back and do it again. she will take a few minutes break and then go swim through it and then dive and then she will go over by the logs and do whatever again, which is why i cant tell if shes just playing or not? Then the next photo is of my healthy glass fish. You would be able to easily see if the gills were red or anything on that fish which is what puzzles me so much. And then theres another photo of my ram and the last photo is of both my rams. The log in the last photo i forgot to mention came from a forest at my house. I had someone soak it in water for 3 days and theres nothing wrong with it that I can tell. It's been in my tank for the winter (probably since maybe november?) and i havent had any deaths until december/january. So im really not sure what could be causing the problem :(

DISCLAIMER: I use only sponge filters so I'm really not equipped to determine whether or not your filter is functioning normally. If, however, I saw a lot of debris I would assume my filter isn't functioning correctly.

I do know that carbon will start releasing captured chemicals/molecules approximately 30 days after being inserted into water. Do you replace the carbon monthly? If not, that might be part of the issue.

Since your glass fish show no signs of gill problems, etc. you could have a chemical problem rather than a disease problem. Again, I'm no expert but it's logical on it's face.

Are you using sand as a substrate? If so, could the particulate matter be coming from the sand? I've never used sand (will start with my new tank) but have heard that one cleans it carefully. Perhaps the debris collected in areas going with the current and weren't agitated until your most recent cleaning.

I'm sure this isn't helpful. Just giving you ideas and places to start. If your pregnant fish isn't constantly at the bubbles, she very well could be playing. Is she gasping at all? Is your Angelfish gasping?

I would seriously consider purchasing a good test kit online. It can be a bit pricey but well worth it when issues like this arise.

Activated carbon does not release things it has adsorbed - once the receptor sites are full, it just becomes more biological media. Too, even if it did, it would only release the things that all of us who don't use carbon don't bother removing in the first place.... so I wouldn't dwell on the AC.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

Really?? Seriously, when I was deciding on what kind of filtration to use I was told in no uncertain terms that activated carbon will release captured chemicals after a month or so. I decided on sponges due to Angels disliking currents but what I was told about carbon also swayed my decision.

See, proof positive that I am no expert!

There are a lot of old wives tales that still persist in this new age of fish keeping. Understanding how activated carbon works and what it does, it's just not true. I mean, aside from some very specific instances where carbon is called for, such as removing medications, there just aren't harmful chemicals in your tank to be adsorbed, let alone to then be released later.

In order to recharge AC (get it to dump what it had adsorbed), you have to expose it to like 700 degrees in a zero oxygen environment.
