My stingray is acting weird. He frequently swims to the surface and spits out water. Is this a problem?

  • We are currently upgrading MFK. thanks! -neo
I encountered similiar behavior a few times in the beginning days me of keeping stingray. I don't know it from friends or other people, so I can only pull information from a very limited pool. If I an wrong, someone please correct me.

When mine did that, they did that because they were very upset. One time, a subadult female always came up to the surface and spit water against the covers, to the point of it leaking all over the floor. She did that for a few days and then just suddenly died from one moment to another, still eating the days before and being active just 20 min before I found her dead. I was to inexperienced back then, but my water was not the most stable (to soft and nothing to stabilize like tannins) which inevitably lead to something bad happening causing me to nearly lose all my Stingrays and some other fish. What exactly killed her I am not sure, but I think it was a sudden burst of nitrit.

Another time when my Stingrays refused to settle on the ground and were always on the glas or in the surface plants was because some fish were nibbling on their rim.

Sometimes, especially when you keep them alone, rays are very active, but if it seems suspiciously much, they are upset about something.

Please let me ask you:

Is this your first time keeping them?
Is it alone/what are the tankmates?
What are the water parameters?
What is the ground supstrate?
Do can think of anything that might upset your animal?

I don't want to generate panic, but it is good to be sure.
