Sick and dieing Motoro

  • We are currently upgrading MFK. thanks! -neo
I have 4 rays at 4 inches in a 60 gallon tank, filtered over fluval 404 and fluval 4 internal, 50% waterchange every week, no problem at all?:)

you're lucky then. depends on how much you feed them too. once a day, or multiple times? i wouldn't dare leave a 60gal tank with 4 rays in it for a week with only a half water change. especially in their prime growth stage.
 
2 times a day, live cut up nightcrawlers..

hmm, could be why.
i was feeding mine shrimp, brine/mysis shrimp frozen cubes, bloodworm cubes, blackworms, cut nightcrawlers, pellets, silversides, tilapia, etc.

not only their bioload but add in the food fouling the water. the pellets, fish and cubes were awful for the water quality. i ended up cutting back to nightcrawlers, blackworms and tilapia only
 
Not to take away from you loss, and I am sorry for that. It's hard to lose a fish,esp a ray. I know.. But just reading on the first page... there are two people with rays in small tanks.. People please understand, you cannot keep a ray in a small tank. They need room to swim as well as the gallons to help reduce the bio load. Just because your rays are alive and swimming around, doesn't mean you are not causing them harm. Ammonia can kill them quick or slow.
Any ray in a tank under 100 gallons in my opinion is too small. And that is just as pups. Tanks need to get bigger as they grow or get a large one to start with.

Again, sorry for your loss. In my opinion it could be a few things. Ammonia poison over time as well as not being able to digest the worm you gave him. It could of cause a back up in him and poisoned him. Being in the smaller tank prob didn't help as he was getting poisoned from both ways.. Bio and ammonia..
 
Sorry dude, I hope the next one works out better. The aro can also put alot of toxins in the water since there heavy eaters and there always moving so they burn it off really fast.
 
I am in the planning stages to build a huge 800 gl plus tank for my catfish that are in my 240, then put my ray and aro in the 240. I will get another ray but knowing now I am going to wait till I have the 240 open.
 
Gues il have to lay in that im not a first time ray keeper anymore..

Seems like your plan is good! Keep it up and never give up:) Sorry about your loss btw, its always sad to see that a ray\animal goes away..

- Best Wishes.
