Very sad news!!!

  • We are currently upgrading MFK. thanks! -neo
What are you feeding the gars and cat fish?
Rays are really pretty fragile. Sounds like filtration and water changes isn't enough. What are the rest of your parameters? How long ago was the last fish added?
Sorry about your loss.

I added the Black Diamond a month or so ago. All the fish eat the frozen blood worms. The Stingray eat what falls out of the Gars Mouths. the Stingrays eat plenty. Also sometimes the catfish will get one of the Cubes before the Gars or will eat what falls out of the Gars mouth. The problem here is not what and how much I'm feeding my fish. It's why they died.
 
Sorry for your loss that really sucks. I have not kept rays because I have never had a big enough tank.....i run a 180 with three times the filtration of yours and I do not believe it could properly support even one ray. Rays are the one of the most demanding fish we can keep in fresh water. The 60 gallon water changes weekly would need to be done daily even with half that bio load. The Rays are way too sensitive and at the same time messy polluting fish that excrete tons of ammonia for such a small set up long term. I believe you got lucky for a while but eventually parameters change.....could be a buildup of nitrates in your filters? Most guys here with rays have 240-300 gallon plus tanks with powerful pumps and large wet/dry filters under the tank. Not many use cannisters at all or just for water polishing.

Only thing that changed was last Wednesday The apartment management placed a bag on the wall for 2 days to test Carbon Dioxide in my apartment. Not sure what was in the bag. Also Saturday one of my Gar freaked out when the Catfish tried to grab food out of its mouth and it jumped out the back of the tank. Everything else has stayed the same.
 
sorry for your losses ?

Ditto on previous responses. The high ammonia is because of the dead rays. A smaller ammonia spike may be responsible for their deaths. Check and make sure all of your electrical equipment is working properly and no wires are exposed.
