[batang_mcdo]

Hi,

I just noticed 1 of my motoro likes to swim around?
is this normal motoro behavior? because normally they like to stay at the buttom.

Also noticed they seem to have a hunch back?
and 1 of them looks like it has been eating simething? like when they are eatting they seem to puff up their back?

anyway here are some of their picture, anything wrong with them?

notice that near the tail part there seems to be a hump?

is this normal?

I have 2 females and a male, they have been with me for aboput 2 months n, size is about 6-7 inches.

thanks.

Looks normal to me...if it's not....My sting ray might have issues to.

thanks i was wondering why 1 of my rays seems to swim at mid level, she's like a piece of paper flapping also noticed here trying to puff her self up? like when eating, but i did not feed her anything when she was puffing up.
after that i fed them some mp and their appettite are quite good.

her back side bumps up when they're full...mine likes to swim to the top, then turn and swim the length of the tank.

My stingrays hump up their backs when they do their business, should be ok! Feed it something easy to digest.

They are normal dude, they get that hump when theyve eaten loads.
