My brother has just got 3 red sword tails. They are friendly with the other fish but do sometimes fin-nip the red dwarf gouramis.

I am wondering how long it takes for a pregnant swordtail fish to give birth.

I am wondering if female swordtails lay on the bottom before giving birth.

I started with 2 swordfish, they are green with a red line down the side. The male has a beautiful long light green tail with a black edge all around. They have mated many times. The male doing that dance he does going forward then backing up to the female. They have had fry about 4 times since I've had them. Almost all have lived and I leave the babies within the tank with all the other fish and they have all made it by hiding in the plants and rocks. Also, some of the bigger fish have gotten use to seeing the fry around. I feed all of them 2 times a day. So just let them be and they will take over the tank in no time. I keep the water temperature at about 80 degrees. The only thing is it seems like all the fry are females, some are 1 inch long and I don't see any swords yet. I guess I'm stuck with 100 females and a male. Lucky fish.

I have 4 swordtails (listed as pineapple swords)in my 30gal long tank: two of each sex. The one male seems to be the "alpha male". This observation was made when watching the his activities as it appears he is trying to mate with one or both of the females. He would chase off the other male, while keeping the two females hurded.

What was very interesting to watch was what appeared to be a mating ritual dance preformed by the male. He would start from a stand still and dart forward about several inches, and just as quickly, do the same in reverse. He didn't turn around, but actually went straight back. He would go back and forth a couple of times... and then rest. I witnessed this behavior a couple of times.

Unfortunately, I don't know the temp of my tank, as I need to get a new one. However I had turned on the heater the other day, as it is getting much cooler in my apartment. I am thinking that the warming of the water has spawned this new activity. I do have some live plants, one which is probably over 3' in length (planted in a corner). I pushed this plant in at several places along its length to keep it from all floating along the top.

Hopefully this will give any fry produced a somewhat safe haven to hide while they grow.

I have a 20 gallon tank with guppies, and albino cory cats. Today I added 2 females and 1 male red swordtail to the tank. While I was introducing the fish to their new home, I noticed that the fish were going crazy eating something at the bottem of the bag. With a closer look I noticed 6 babies at the bottem of the bag. Now I do not know if the babies were caught in the net while buying the fish at the store, or did one of the females have the babies during transport from the store to my home. I bought 3 fish and put 9 in my tank! The babies are in a breeding tank doing very well, and are eating regular flake food that lays at the bottom of their tank. I guess I will need to get a bigger tank now!
