Lost 3 Cories

[Bryterlater]

Hi All

I bought five julii cories at petco and for some reason 3 died, the remaining two are thriving at the moment. The other 3 died within the 2nd day of buying them.

I'm feeling guilty because I only have 2 now. They seem quite content and dart about together...if I can't find any more Julii's is there any point to putting a different cory variety?

My water parameters and temp are good, way under my bioload and cycled tank...I think they may have just been unhealthy from their time at the LFS

Sorry to hear that. Certain stores I don't like buying cories from, as their cories seem super sensitive and tend to die on me. Since they died so soon after you got them, sounds like they probably weren't very healthy.

Some types of cories will school together, some won't. You could just stick with the 2 you have, as long as they are healthy and happy until you find more of the same kind. If you decide to get more cories, try and pick some that have similar markings (I think they're more likely to school together that way).

Don't feel too guilty over it. Just take good care of the survivors.

Just wonderin'... did you take time to acclimate them well before adding them to the tank? Sometimes in the excitement of getting new fish, we overlook this.

They should have some sort of guarantee if you've had them for just two days. If they don't have anymore, just tell them you'll wait until they get more in to replace them. They should be able to get them in their next order.

Hopefully the next batch will be a little hardier. :o

Hi and welcome to AC!

I had the same thing happen to me just about. I got four Three-Striped Cories (which are probably the ones you have) and everything was going great. But then one died. Then a month later another one died. And then a month after that another one died. I only have one left, but I got some new friends for her.

I think if you can't find some Three-Striped in about a month, then I would get another kind. I have three kinds together and they get along great and like to hang out sometimes, but they do prefer hanging out with their own species.

yeah, I definitely acclimated them. I floated them for about 20 minutes, netted and released them.

I found the first body the morning after and went right back and got my money back, the second was later that day and I didn't want to trek back with another dead fish for two dollars, and the last one has diappeared I'm assuming he turned into fishie food.

The last two are VERY active and happy so i hope they'll be fine.

I'll be checking back for more Julii's periodically cause I want the best for them:dance2:

I have a multispecies cory group, and they all seem to recognize each other as family. Sometimes I'll see a cluster of two or three of the same species, but most of the time they seem to be in small mixed groups of 3 to 8. I suspect your cories died of a combination of parasites and stress. That's what killed a lot of my cories. I would see a new species in the pet store and get a half-dozen, only to have 2 or 3 die within a few days. The survivors have invariably been healthy, and I've never lost one that's been in my tank longer than 10 days or so. Most cories are wild-caught imports, and wild-caught fish almost always carry a moderate parasite load. The stress of capture and adjusting to aquarium life weakens the fish, which causes the parasites that are no big deal to a healthy cory to be a fatal problem. From conversations I've had with two LFS owners, I would guess that two-thirds of the wild cories that make it to pet shops end up dying either in the store or in customers' tanks. From that, I would be willing to hazard a guess that perhaps only one in ten survives the whole ordeal from capture to healthy aquarium resident. I suggest you not get any more C. trilineatus. Instead, add a few C. aeneus (aka bronze or green cories) or peppered cories to your tank. Those are almost always captive bred, and if you get albinos I guarantee they're captive bred. You should have no losses on those.

[Bryterlater]

I checked out species differences and mine are definitely Julii's and not C. trilineatus.

Does anyone know if they are wild caught? if so, I won't purchase any more because I'm really not a fan of removing native species from their natural environment. I'm gonna try and google it, but i suspect findign the anser might be tough!

Thanks!

Hi,

Yep, I'm pretty sure Juliis are wild caught.

I had 5 panda cory and within 48 hours, 4 died. It's been a week and I have one tiny little guy left. I tested the LFS water and it was sky high nitrate so sometimes, it's the LFS. This LFS was locally owned, salt etc I was really surprised. I won't go back.

Since cories seem to be quite sensitive to water conditions, I usually acclimate them over a couple hours. Every 15 minutes or so I would add a little tank water into the bag (with a turkey baster). I also do a 25% water change daily for a few days until their stress levels go down. This is probably a little overkill, but I like the results... Also, your Julli cories might school with other cories. I have 6 sterba's cories sharing a tank with 3 bronze cories and they school around with each other.

[guppygal]

When I got my Julii's from Petco I also took an hour for them to acclimate before putting them into the QT tank. So far I have had all 4 for 4 months now. I have one that looks a little pale but so far they are all doing well.

[Bryterlater]

You know...the gradual addition of tank water USED to be my method...then I read bunch of stuff recently that suggested it wasn't a good idea to do that...rather just get the fish acclimated to temperature, net them them add to tank...

I should have stuck to the tried and true old routine

[Bryterlater]

wanted to add...

Sometimes reading TOO much isn't a good thing :read:

I guess it just depends on what is more stressful: being inside a small plastic bag or exposure to different water chemistry:huh:
