Answer 2

There are numerous ways your fish could have died...
- disease, your fish could have become sickened, weakened, then to weak to live.
- Not enough algae for the cory to munch on in your tank.
- Not enough friends, sounds weird, but i know cories do best in groups.
- Temperature could be either too warm, or too cold.
- The water parameters could be off, it is normal to lose a fish or two if you are still cycling your tank, or fish cycling.
- The fish could have been bullied to death by another fish, if any are present.
- Too much stress, if you released the fish too quickly without proper acclimation, and kept poking him to move, etc.
- Not enough oxygen in the tank water, not enough filtration, poor water quality.

Cory cats are sensitive to a number of different things. Here are a few...

Cory cats are schooling fish. They like schools of three or more and often become stressed if they are alone. Safety in numbers is instinct. Two, cory cats are sensitive to chemicals and heavy metals. My area has a high concentration of copper that does a number on several aquatic species. A good water conditioner will take care of this, such as stress coat. Certain medications are absorbed by algae, such as victoria green and malachite green. when they algae is eaten by fish, the high concentration of chemicals in the food source can kill them. Three, is enough food making it to the catfish? No fish alive "eats" poop. Cory cats need a good sinking pellet food to survive, and if the flake or other foods you feed aren't getting to him, he'll strarve. Four, cory cats are near the gravel all the time. Your gravel is where the majority of your bacteria grows. While a cetain level of bacteria in your tank is good and neccessary, too much can kill your fish. With the catfish so near that source, he could have suffered. Have you water tested for high levels of ammonia, nitrate, and nitrite. If these levels are elevated, perform a 20-30% water change. You should do this weekly while adding a water conditioner to help keep your water quality at optimum level. Five, paraites such as ich breed in the gravel. Bottom feeders are often the first to get these infestations as they are closest to the source. Keep an eye on the rest of your fish for odd behavior and growths. Post descriptions if needed for help with treatment. Lastly, cory cats are often wild caught. This means that they come with a variety of natural internal and external paracites. Over time, these paracites will kill the fish. If it is internal, it would be very difficult to pinpoint the issue.

To be safe, dose you tank according to the directions with a good water conditioner. Have your water tested for ammonia, nitrate, and nitrite. Perform a water change of 20-30% if needed, siphoning from the gravel. Incoorporate an anit-paracitic food into your fishs' diet. Jungle makes one and petsmart sells in. They also sell anti-bacterial food as well. Keep an eye on the rest of your fish for listlessness, lack of appetite, growths, and odd behavior. Identify the issue and treat. Most diseases, infections, and infestations will present within 2 weeks. Once you are certain your water quality is good, your fish are healthy, and there are no other issues, you can try fish again. If you have the room (each corry needs about three gallons) buy a group of three or more cory cats. Also get them a sinking bottom feeder pellet. Aqaurian makes a really good one that retails under three bucks. Then sit back and enjoy.

Good luck and happy fish keeping!

Answer 4

what else was in the tank and how large is your tank? when was your last water change? do you add aquarium salt? corys are not tolerant of any salt in their water. as others have said, a cory is a social fish, they need to be in groups, did he have any friends? did you notice anything odd about his behaviour or anything on him that was unusual? how long have you had him?

what was the substrate on the bottom of your tank? were his barbels intact?

it could have been a number of things without knowing what potential symptoms could have been. what did you feed him? corys are scavengers but need to be supplemented with their own foods, they do NOT eat algae, in fact they prefer meat! and are quite partial to bloodworms and brine shrimp.

there could be a possibility he already had an internal infection, which sometimes offers no, or very little, exterior symptoms visable to an untrained eye and one day they just succumb!

Answer 5

You, as should all fish keepers, need to get a good book that describes fish diseases with symptoms, pictures and cures listed and study it well. This should be done before you ever buy a fish. You don't even need to buy the book because libraries have them.

Answer 6

did you change the water?

when you do that, dont use tap water because it contains little chlorine that's not good for the fish. also the water isn't contaminated enough for the fish,.

Answer 7

dirty water? black algea? new food? overfeeding? ammonia too high? ph too high or low? temp too high or low? aggressiveness in the tank?check all your levels in the tank. id need to know what kind of fish you keep to know if they belong as tank mates.

Answer 8

Answer 9
