I just started a new 55 gallon tank a week and a half ago and I initially put 6 tetras to cycle it and then added four large angelfish from a different tank. Yesterday, I added a red parrot and a gold severum and when I got home today I saw one of my angels (which is about two years old) dead. I was wondering whether it could have been a disease, or the addition of new fish, or perhaps my tank is too crowded, or maybe the fact that its a new tank. I check all the water parameters and everything looks good. Any ideas? Also, Ive noticed that some of my fish have what seems to be bloodshot eyes. Usually one of the two eyes is redish. Is this normal or is it a sign of sickness? THANK YOU SO MUCH!

Are your ammonia and nitrite levels at "0", because if they aren't your tank isn't cycled
And it sounds like ammonia poisening
As for the angels, they are extremly sensitive, and you can't put them in an not established tank
hope that helps
good luck

If I understand correctly, u got a new filter recently.... All the beneficial bacteria that was in it has now been removed... So now there isnt enough of that bacteria to break down all the toxins like ammomia from fish waste. My best advice is to go to your local fish store and ask for some of their used filter media (keep it wet in some tank water so the bacteria doesnt die). That will have the bacteria on it that you will need to get everything balanced out again. Keep it in your tank for 2 to 3 weeks to make sure it all transfers into your tank. Also, get yourself a water test kit if you dont have one already, just check it like once a month or so. Its always a good idea to be informed about whats going on in your tank. Api LIQUID master test kit is very reliable. Liquid kits are the absolute most accurate, test strips are kind of sketchy.

You made the mistake of cycling your tank only once instead of two or three times to get it stabilized. So your older fish could not adapt to the new tank. Cycling of a tank requires more than once to prevent ammonia spikes. Usually two to three times with trash or small fish that can handle the ups and downs. You need to figure out whether or not the sick fish can handle another move to the older tank or just see if they weather the changes. Good luck.

Stress is possibly a factor, though something having to do with water quality sounds to be the culprit. Try performing a 50% water change with distilled water. That should soften it upfor your angels while you try to "cycle" the tank. If your original aquarium is still running try adding some "dirty" gravel from there as a way of introducing the beneficial bacteria from their previous tank to jump start the biological process

That tank is way over stocked, it could have been ammonia poisoning. You cycled the tank with small fish that don't have big waste so the bio load was small, the bacteria colonies where small, then you added these big fish with huge bio loads and the bacteria colonies couldn't handle all the ammonia.
