The pictures suck, but you try to take a picture of two moving objects that are not in coordination with a cell phone camera
Red: young streamlined boy with a long caudal :) All red!
Georgie: .... well, you'll see.
FIRST PICTURE is to show his rot, and how thin parts of his fins are

well I guess I would be sick too if I had been with goldfish, and I were a betta
Red was in his water changing cup because I'm here, there, doing everything everywhere including water changes xD So I took that opportunity LOL. Anyways, the distance between them in the pictures, is only the container itself. They both were pressed right up against the sides of that thing flaring away

(tch...boys...) So that shows you the size without them being RIGHT there beside each other without safety... Red wasn't even daunted at the size of his "rival"

I had them in there and I had a heart attack x.x there really is a difference! I'm not crazy! (well, not for this I'm not :) )
o.o; just to note, Red is not a dinky itty bitty betta.
