Need Help ASAP... Is this normal

How long has that tank been running and how deep is the sand. I can't say I have seen a rays disk edge to that. He looks agitated. How does his belly look? Does it have red patches on it? My first thought is something bacterial is going on.

Obvious question time: water params?

this has happened to me with a prize of a motoro female do major water changes fast. what type of sand is that? And when you do water changes do u stir up the sand ? the sand can hold gas's of toxic waste that you dont know are there and will irratate the rays disc ! it will then slide up and down on the tank walls almost to save its self from the burning

whts the ammonia level?

do u know how the nitrogen cycle works?

a 1 week old tank is deff not cycled, unless u transfered alot of media from an existing tank

hym last night no good buddy I think that was to fast of a jump sounds like you jumped the gun here and did everything to fast remove it water change it quick

You in essence took away the beneficial bacteria that was supporting the tank so its just as if you just started the tank. You're doing too much. The key with rays is stability. Put the other filter back on immediately and do water changes regularly. Leave the sand and everything else alone bro. Put the temp on 82-84 and use two or more table spoons of salt per gallon of water in your tank.

I've seen this ray in person and she is quite a gem...Would be a shame to lose her.

Good luck!
