oh yeah, my chasing platy

in the tank (20g):
1 red platy (male)
1 gold crescent platy, I think (male)
1 black platy (female)...already pregnant, about a dozen babies
1 swordtail (male)
6 neon tetras (no idea)
3 diamond tetras (no idea)

The red platy is chasing the gold platy on a consistent basis. I got the tank and the platies back on Saturday. I'd rather not replace the red platy with a female one. A non-platy would probably be the replacement.
Could the chasing go away if I wait a few more days? Like 1 week total? Or should I remove the red platy right away?

correction on the black platy, it's a black female swordtail...oops

so:
2 swordtails: 1 male, 1 female
5 platies: 2 male, 3 female (new)
6 neon tetras
3 diamond tetras
~12 baby swordtails, in a pen

Yeah, it's crowded I know. I'll probably remove 1 male platy and most all of the baby swordtails once they've grown some (1 month?). Hmmm, maybe even both of the swordtails. I just gotta find a home for them since I have only 1 tank.

my dilemma....

1) return fish to the lfs: aggressive male platy, a female platy, male swordtail, and a diamond tetra. this leaves:
1 female swordtail
1 male platy, 2 female platies
6 neon tetra
2 diamond tetras
the baby swordtails.

2) get another tank: put all the platy in the new tank. Swordtails maybe as well.

3) Return the four fish AND get a new tank...for the babies


I'm not too crazy about getting a new tank since I just got my first tank about a week ago.

so what does everyone do when they get a crapload of babies that they can't handle (tank size-wise)?? Flush em? My gf and I can't bring ourselves to flushing these fish down the toilet .

I might do that once my gf warms up to the idea . The babies are protected in a fish net breeder right now.

Yeah, it's waaaay too crowded in there right now. The fish are going even more nuts when I feed them and even the neons are chasing away the male swordtail. I got the rule of thumb mixed up and thought it was 1 FISH per gallon instead of 1 INCH of fish per gallon

<-noob

We're going to go with option 1. With those 4 fish out, is our fish population ok for our 20 gal.? We may get a 2nd tank, but not for a while.
