What is wrong with my stingray?

  • We are currently upgrading MFK. thanks! -neo
I think my bigger ray is mature but they are both males. The only thing in the tank is driftwood and it is pretty smooth all around. I will check the pleco out tonight once the lights are off. Is there a good place to buy heater guards I haven't seen any at my lfs.
 
My older one was bought on 10-10-06 and he is about 9 inches across, and my other one was bought on 10-30-07and is about 5 inches across.

you could turn the lights out and sit back and see what's going on

Yeah it's the smaller one.

Hmmm...I am just guestamating let me go measure.

Well he is 6 inches so Ii was pretty close. He eats like crazy so I'm not sure I just assumed he was growing fine. How big to you think he should be?
 
Don't worry about the growth rate, as long as it is eating he is good. I've had many motoros grow faster than other motoros--including rays from the same litter.--Like any other animal some grow faster than others and some grow larger than others, even of the same breed.

Your bigger ray may not be able to distinguish your smaller male as a male because it can't sense his hormones until it too matures. When I removed my breeding male motoro from the female and moved him into a tank with males only, for about a week he was biting and trying to mate with my male orbignyi and has now stopped.
