Stingray swimming near top, sticking nose out...

  • We are currently upgrading MFK. thanks! -neo
This will be a necro post but i was searching on the internet for an answer.

and MFK saves the day again
 
He keeps swimming near the top of the surface, ocassionally sticking his nose out of the water. Although its not constant, its more than he was doing yesterday, which was zero. (Ive had him for 3 days) He's in there with a lot of tetra's (they were cycling the tank for about 3 weeks)
nitrate=0
ammonia =.5 ppm
nitrite=0
Temperature=84 F
Question: I've never had a stingray nor seen anyone elses tank for an extended amount of time. Is this normal behavior?

Thanks
I would be more concerned with the .5 ammonia then anything. That is a normal ray activity
 
Are we not missing the zero nitrates???
Normal Ray behaviour in good water but good water should have nitrate present
 
old post but if it helps anyone in futuer the rays will stick to the surface if there is low oxygen and they will swim in the inlets to keep out of the way of other fish if they are getting bullied / unwanted breeding attempts . this is from my experience. seporate and oxygenate. good luck .

Thank you for the information, just had a ray and it does this sometimes. MFK threads always answer my concerns, sorry if a very old post got bumped - just wanted to thank everyone for the info!
