Howdy neighbor, I'm like 10-15 miles east of your zipcode.
For life? That really depends on the compatibility of the fish. Especially on how aggressive or passionate the male is. From what I seen and hear, depending on the type and condition of your female, some will lay eggs every 2-4 weeks with or without a male. I read some where that a good size ratio to have is 2 to 1 for male to female. I know my bigger female will and have beaten the crap out my smaller male. LOL
There are a number of ways you can try:
--Create a bond for them by giving them some small target fish to play around 1st, and then let go divider.
--The another way is cut a hole in your divider big enough for the female to get in and out. That is how I got my fader and green texas together.
--If the above two don't work, then you will have wait for the egg tube to show then let go the divider.
---And if that does work... ummm no show/no go for the two I guess...
Once they are together... I would recommend hiding places for the female. Sometime, for some reason -just to make sure he is still the king of the tank?-, my male will flare up and chase after the female for no reason.
I am not an expert, but these are things I've tried and worked multiple times.
Good Luck!
