Guppy Guy Posted June 2, 2022 Share Posted June 2, 2022 (edited) Hi all. As you may have seen, I recently lost one of my favorite angelfish to an unknown cause. That wasn’t the first time it happened though, it was about the forth. I created this to try and figure out what it is, where it comes from, how to prevent it, and how to cure it. I want to hear all input and opinions, as well as any theories you may have. I will put my details below. Thanks for contributing everyone!(If you don’t want to read all this, only the 2nd and last paragraphs are vital) The first memorable case I had was with a Dalmatian molly about a year ago. The second case was a guppy, and the third was a swordtail. All the victims were in perfect health and perfect water parameters to begin with. All had been in the tank for at least a year, though the angelfish and swordtail had been in it for 3 years. There were no obvious symptoms that slowly became noticeable as with most diseases. It was just “first day, perfect health, second day, almost dead, third day, dead” Every. Single. Time. Let me break that down. The first day, as mentioned above, the fish was perfectly fine. Acting normal, looked normal, and behaved normal. The second day, they just dropped. All the victims would kind of shimmy around for the first hour or so, and then drop to the bottom of the tank and sit there on their side. They all would try to swim around, but just didn’t have the strength to. The worst is on the third day though. In the morning, I would have already moved them to a hospital tank, medicated with various medications I will talk about later. They would try to eat the food I put in front of them, but don’t have the strength to swallow it. It truly is the most pitiful thing I’ve ever seen, and I hate re-seeing it every time a fish gets this. Then about midday, the fish improves. It can eat normally, acknowledge my presence, and almost swim upright. Then it suddenly dies out of nowhere. It also happened with every fish. The medications I used all gave the same results as mentioned above. I tried plain aquarium salt, pravipro, marycen, pimafix and melafix, focus, metroplex, and stress coat. The water parameters were the same as the tank it came out of(temp 76F, ph 7.5) and I used a 1:3 ratio of new water to old tank water. I also put substrate in the tank to help cycle it, as well as established filter media and an extra air stone. It is worth noting that all these fish were in the same tank, and that tank is still running today, as is this problem. The tank they all came out of is a used 36 gallon bow front, and when I get it, it had been empty for 15 years, so no cross-contamination. There is a bubbling ship decoration that came with the tank, and PVC pipes that add shelter and style to the tank(they look old since they are covered in algae). The substrate is a 2:3 ratio of sand to gravel. The light is a fluval aquasky 3.0, the heater is a Eheim jäger, the filter is a fluval 307, and the air pump is an aqueon quietflow(I think). I will list the fish, though know that not all of these were in here at once. The tank has always been reasonably stocked. The fish include 3 angels(now 2 😞), between 3 and 5 guppies(still there), a swordtail(one of the victims), a molly(first victim), a swordtail(victim), a whiptail catfish(still there), 4 zebra danios(still there), and snails(I try to remove them, but they always come back). I don’t know if this is a common issue or not, or where to begin looking for it. If you have had similar experiences, please share. I am thinking it is some kind of bacterial infection, but I would like to know your theories as well. If I can come to some kind of conclusion, I will share and hopefully be able to update with good news. I will also be contacting local fish stores and interviewing many people, so I will post the results here. Thanks in advance for sharing! Edit: it is worth noting that I posted this more for research then help. Edited June 2, 2022 by Guppy Guy Link to comment Share on other sites More sharing options...
