My stingray died, I don't know why and I feel like complete garbage.. PLEASE HELP

  • We are currently upgrading MFK. thanks! -neo
I think u had a fish that just wasnt perfectly healthy, and what I mean is that just like humans and dogs , etc. Some of us or them die as babies for no great reason. Just one day, we or its dead. It could be an internal issue or a genetic issue. He could have had a health issue that wasnt apparent until u found it deceased. Its unfortunate but it can happen. Ive seen fish perfectly healthy one day and the next be dead. It SUX alot but thats life I guess. A way of population control. U say it didn't have any visual health issues or damage from any tankmates so there's no real answer. Like others said, ur temp is a little high and if u dont have a good amount of O2 in the water, the total O2 saturation would be low and rays love high oxygen levels so that could be an issue as well. Also they have a very big appetite so if u dont feed them quite a bit, they will suffer and die from slow starvation so it could have been one of a few reasons. Im sorry for ur loss, been there too. Good luck in the future bud,

Thanks so much, he always acted strange compared to other stingrays, he never buried himself but was active and was very social. I fed him black worms every day and kept him nice and plump, I don't think it was the temperature since his behavior didn't change when the temperature was raised a week ago. A birth defect was one of my suspicions, maybe he had a weaker immune system? And for oxygen I have a powerful double header airpump that pumps ALOT of air. I'm starting to believe maybe he was born early since rays are known to give early birth when in stress... Is there anything you think I should do if I ever plan on getting another ray? I did a water change again today and added some more aquarium salt to kill any diseases or parasites he might have left behind. Basically Is there anything I should know to avoid this in the future? Thanks again for yours and everyone's input!!
 
Your dont have enough filtration and you dont do enough water changes.

How is double the filtration and 1-3 20% water changes/week not enough? And Also if you read I've ruled out water quality since none of my other fish were affected and I did a water change and added aquarium salt a few days before. Only post if you're going to actually add any materialistic advice relevant to the thread...
 
Could have been water but most likely not a little amonia spike can be catastrophic for a ray. Water changes where fine but keep consistent 1 2 or 3 water changes a week don't flip flop as much as possible. Why do you need to change water once one week and three times the next? I do agree tho with owning rays more filtration is better have way more media then is needed for your bio load and higher turnover rate then you have is best.
The filtration "ratings" don't really mean anything when you have that big of a bio load in your tank, yes with a moderate stocked tank they are fine but you have a lot in that tank for those filters to keep up with, it is not possible in my opinion. I am not bashing or saying you are doing anything wrong I have tried the same thing you are doing with the same results. Now that I have learned my leasing I have a big sump with 25l k1, 10 gallons bio balls, 3l ceramic rings and 15 plants in a 125 under my 180. No more headaches.

Do you think his fish or overloading the media do you think a feeding and check the water half hour later would show some spiking? The rest of the fish he has can handle a bit of spiking with no immediate stress or visible harm to the fish
 
Temp is to high and most likely a contributing factor since you jumped it up to 88 the week prior. What research made you decide on this temp for any of the fish in that tank?

Filtration is light. You need to look at gph and what exact media is in it and what head loss you have from the canister.

Water changes don't sound frequent enough for your filtration.

WhAt were your exact water params? You keep stating the other fish are fine so it couldn't be the water quality but that doesn't mean anything especially with rays.

Pushing the ray down by hand when it's already stressed didn't help and I'm not sure what you did to the ray to yank it's stinger out but you caused it that much more stress there.

I would rethink some practices you are using prior to getting another and good luck in the future

Thanks for your advice! He was on the bottom when I pulled the stinger from the net, I gently grabbed his stinger and not the tail and untangled it from the net. But I do still think it caused him a great deal of stress. Thanks again!
 
1st: Filtration is lacking! Please do tell us what filters you're actually using. You'd be lucky to even be hitting the minimum needed with a lighter stock.

2nd: Your temps are too high. You'd also be surprised at the amount the O2 that is depleted at those temps

Also, you seem to know everything already. Any advice given to you is met with a quick excuse as why "it can't be". From your responses. You should do a bit more research before you purchase your next fish.
