i had 2 corys die over the last few days as well as a Bristlenose Plecostomids now in that time i strated feeding them on a new typ of fish food i got its called super soft soft &moist fish food with krill is there a reason why that might have killed them ? in that time i put a aqua master multi cure medicine but thats some thing i do now and again and i never had problem befor all the same i changed the water after died to clear the tank of the medicine just incase but i dont think it was that i realy want to no if the food can do any thing to them

- Start date
did you check the expiriry date?
yep its good i was look at the back just then and i see where it says feeding instructions and it says feed sparingly cuz its a very rich food feed only as much as fish will eat within a few minutes if use right this food will not cloud water ................i dont think i gave them to much but if i had do u think that means it could kill the fish 
I don't think it would kill the fish, probly just make them fat 
. Seems very interesting, was their any sign of sickness? I would personally post a new topic on tropical fish emergencies as you may need some words of wisdom from Wilder.
. Seems very interesting, was their any sign of sickness? I would personally post a new topic on tropical fish emergencies as you may need some words of wisdom from Wilder.problem is what would i say cuz the rest are 100% okay at this point they showed no sigh of sickness oh wait one was a bit wobbly then soon died but i think that was cuz he was dieing not cuz of a sickness they were both of my bigger ones
Then i'm pretty clueless as to what it is! If you can think of anything bumps on the fish, fish changing color, ect. That would help. I would still do a post tfe. Have you tested your water latley?
water tested fine and i evan changed it too be shore one of the body was a light color but i think that was cuz it was day old my tank has a few plants in it so i did not see its body right away i spose i will post on the tropical fish emergencies place but dont think they can do much
Hi Fizban
Are your ammonia and nitrite at 0? How's the reading on nitrates?
Please look for any symptoms that your remaining fish might have and tell us about them. I see you post in Gouramis and Anabantoids. Do you have any aggressive gouramis, etc? What's the temperature of your tank water and what kind of substrate do you have?

Hi Fizban
Your parameters are good, so being as you are having a problem with corys I would always suspect a bacterial infection of some kind. Perhaps they didn't eat all of their new food. I also read on your thread in Emergencies that you're feeding them Wardley's Shrimp Pellets. I suggest that you get rid of them. Wardley's original shrimp pellets used to be good, but some time ago they changed their recipe. Since then they leave a lot of residue which can filter down into the substrate and cause problems. When I was using it, I found it actually fermenting in the gravel.
Please give your substrate a good vacuuming, if you haven't already.
Also, what kind of corys do you have? I noticed that you keep the temperature very high. Unless you have a kind of cory that need that kind of heat, it might be better to lower it. High temperatures also help make the harmful bacteria grow faster, so it's something you will want to think about.
One more thing that's important is to keep good water circulation at the surface of the water. Low oxygen content in a cory tank can lead to problems too, especially when the temperature is high.

hmmmm
i kind of alway have had my temperature up that high for most of my tropical fish i find that they seem to injoy it on the warmer side ruther then the cool side of what it says the fish should have oh i have 3 diffrent typs in there there was 4 but one of the ones that died was the last of his kind the 3 i have now are the a Bronze Cory an albino cory and i think the others called a bandit cory
i thort a higher temperature helped with stoping some bad things growing i was shore i saw that some where on a post

Warmer water will kill off ich, but corys don't seem to have a problem with that anyway. They are more likely to get bacterial infections and that's the problem you should try to avoid. High temperature will make the environment comfortable for harmful bacteria to grow in, while cooler temperatures will slow it down.
You might also have heard that keeping the temperature up will cause your fish to eat more and to grow faster, but it does this by speeding up their metabolisms. On the down side, it also causes them to age faster and shortens their lifespans. The ideal temperature for any kind of fish is whatever it usually is in their natural environment.
Your bronze and albinos are most likely C. aeneus, which prefer a temperature between 70 and 76 degrees F. The bandit, a C. metae, does best between 70 and 75 degrees.

cool hmm and yes i rember it was ich i was think of and it was to do with gouramis in my other tank oh i have a few bronze corys in there as well im ruther suprised that they have no problem with the gouramis cuz i had herd gouramis are agressive fish i herd that after i had about 6 of 3 spots kind and 2 moonlight both moon lights are male and the others are 3 males and 3 females i have had them together for a few years now with no problems .................oh what temp would you say to use if your keeping ones that need a bit difrent temp? the pet told me most do well arownd 28 f
Hi Fizban
C. sterbai are the warm water corys I most often see for sale in lfs, although not all the time. They are big and beautiful and thrive in water at 28 degrees C. (82.4 F.) That's a lot of difference in temperature and will matter to the corys. Your lfs gave you the wrong information about corys as they so often do.
If your gouramis don't bother the corys, it's good. Gouramis seem to vary in temperament and perhaps they are too busy worrying about each other to bother with the corys. Just be aware that if they chase them, even if they are not necessarily doing visable damage, it will cause stress to the corys and could lead to weakened immune systems. If that happens it would be best to move them to another tank.

C. sterbai hmmm yes i think i have 2 of them in my other tank with the gouramis are there any other typs you no of that do well at warm temperatures cuz i love to mix corys ....oh and 28 degrees C is about what i keep them at some times if im trying to breed the gouramis it gos to 30 they seem to want to breed if the temperature suddenly changers like that i may have mucked up when typing in the temperature last time .....the guy who works at the place i get my fish from told me the other day that they were geting a rare faily new breed of cory in at least the supplyers said they were .....i cant rember what he called them but to me they sound some what like Corydoras schwartzi maby the dots are smaller then Corydoras schwartzi he said they were a light color but how light is light i wont no till i see them i guess any idear what they maybe the guys a friend of mine and said i could have first pick at them when there in the shop in 2 weeks if i want ... i think they come in at the end of this week but hes going to keep them at his place a week to see how they go B)
