Thought these photos would show the difference a couple of days of being jarred and carded makes for a juvie male betta. He was jarred mainly for size, but I did notice he was starting to get a little "nippy" with his siblings around feeding time.
These photos were taken 2 days apart. The first on the day he was jarred, the next, today after a flaring session. His colours have deepened, his caudal spread has improved and I am sure I can see a little fin growth...
1. Taken 06/11/11 on the day he was jarred...
2. Today, 2 days later (please excuse the dirty glass)
