This is a longish post, I'm trying to provide as much information as I can recall over the past few days in hopes of figuring out what happened.

I've been running this 10g tank for 5 months, it's been under my dad's care for two months since I was in college as well as a geological expedition. I get back and find my betta dead. No big deal, that happens, he was fully grown when I got him.

Oh, let me run the list of the tank before all this crap happened:

1 Betta
2 Otos
1 Upside down Cat
2 Cories
5 Neon tetras

This tank was lush with activity until that betta died.

I make my way to Walmart, buy testing supplies and a bigger filter (a 10-30 gal, 150g/hr) and hook that bad boy up to help get some excess waste out. Mind you this was at 2AM, I was only home for 2 hours and kind of irritated.


The next morning, I find a dead neon. Now, I think nothing of it, fish come and go. But shortly after, I notice my other neons kind of swimming at the surface at a 45 degree angle. They all end up dying over the next few days and their backs seems to have turned darker black, but not too much. An Oto dies too, probably from stress when I was moving plants around, more or less tending to a mass of java moss that accumulated, did not tell my dad to mess with it thinking he'd like some when I set his tank up (which I did today hahaha). So I threw half a 10 gallon tank worth of java moss and had to re-root plants.

My water tests show my usual chemical killers were in check, and my dad had been taking care of it as I directed.

So I go to Pet Supplies Plus today and get a new betta, he seems to be doing good, he's a still growing CT, beautiful red coloring and all that. He's quarantined of course, until I figure out what the heck is going on. I come back and I notice my other Otos eyes are white, with the white sticking out. It wasn't ich, I've seen ich in Otos. It was some other worm or parasite. He ends up dying. While at Pet Supplies, I got wide-range medications and threw that in the tank with some salt.

Let's have a count shall we?

2 Cories
1 Upsidedown Catfish

Only the hardiest survive, I suppose.

Well, earlier this evening, my Syno decided to just swim around in the light and kind of skim the top of the water. I think no biggie, my dad usually turns the light off at that time and he's hungry. But then I start to worry since all the other fish that died started acting differently. So I throw in food for the 3 catfish and turn off the light.

I checked on them right before I started typing this and my Syno seems to have settled down and is chilling in a hiding spot again.

I have noticed my two cories are gulping air more often or I just am noticing it from not being around my fish for so long... and right after one gulps air, the other does too.


Any speculations on as to what happened would be greatly appreciated.

The medication I am using is Maracyn TC, it covers Popeye, gill disease and fin rot. I went broad since I think that oto had popeye, but I also have more meds I might dose up after I run these.
 
the symptoms that your fish are displaying (possible breathing issues, cloudy eye/popeye) point to symptoms caused by water quality issues.

what are your pH, ammonia, nitrite and nitrate levels on this tank?

how often do you water change it and how much each time?

more info will help us to help your problem.
 
Did your dad do w/cs while you were gone? Also make sure you use a liquid test instead of a strip............
 
My dad did weekly 25-30% water changes and monthly ~50% water changes for the two months I was not here.

I tested my nitrates and nitrites shortly after arriving home and they were all but absent, so the source of the mass deaths weren't from nitrates, I did tests after each fish died and all came up in the safe levels or lower.

I don't mean to sound like I know anything, but I doubt my water quality was an issue since my dad religiously did water changes and checked the fishes out for odd behavior, but I hope this was enough information so I know what went wrong.

:D

Your ammonia and nitrites should be at zero
nitrates must be under 50 for even the hardiest to survive, 30 is good, try to aim for 20 or under even if it might not be possible
 
see, popeye never happens in tanks with good water quality. same with the cloudy white film over the eye. they are bacterial infections but these infections only affect fish under stress from water quality.

thats why the symptoms of your fish immediately point to water quality issues.

even though Dad was doing water changes, he may have been overfeeding the tank.

so you can run into a situation where the water changes are being done, but they are not enough to compensate for the over feeding of the tank..so you can still run into issues.

just trying to figure out what is the root cause of these problems.
 
Now that I think about it, he said he did start feeding them more since he felt that they weren't getting enough food. That is not an issue anymore seeing that I have 3 fish in the tank and thoroughly cleaned my water.

And yes, my nitrates and nitrites were 0, did not mean to make that vague.

Thanks for the problem solving, but if there's additional ideas, I'm open to them. Now to make sure my tank is safe and start slowly introducing new fish. :)

When you setup this filter, did you take the old filter off or leave it running as well?

If you just took it off, then you could have caused your tank re- cycle.
 
nitrates cannot be at zero, thats almost impossible...
