Egg spots are nt a 100% tell for sex, I have a few males with egg spots
But the guy on the left is DEF. a boy, and to be safe, he should be house solo
Yes, mabe it worked well at a petstore... but then again, I know may of us who have bettas who were kept in horrible conditions.. the tiny cups and dirtywater "worked well" at the store, but as owners... we should strive for more than "worked well"
This boy is STILL at the store he is from, he has been in these conditions for months and survived.... but again "working well/surviving" and "doing well/thriving" are two different things
