All 4 of them
It was fun to see them fight. They did not harm each other but only chased each other around
Fighting
They did like spending time outside the water too.
They were doing well and one of the females soon had eggs but before the eggs could hatch the female died
I then decided to move back to Delhi and packed and brought them with me as I did not want to part with them. Unfortunately 1 more died before I left Chennai and 1 after coming to Delhi, I guess being in a water bag for over 48hrs really stressed them out. So I was left with only 1.

One characteristic of theirs anyone who has kept them will tell you about is that they are great escape artists. From the day you get them they have only 1 aim - ESCAPE!
I had always been careful of that and always had a tight hood so they would not get out. One day the filter conked and the water got really messy so had to do a complete water change. I put him in a bucket and added a an air-stone and left him overnight. Next morning he wasn't there, I looked all over the house and could not find him. I gave up and was really sad
A little while later the house cleaner came and I heard her scream! The whole family rushed to see what had happened and we saw that the bugger was sitting behind the dustbin in the kitchen 
He was completely dry but as soon as I put him back in the water he was normal again.
They are great to interact with and are much more fun than fish or shrimp. This 1 in particular was always ready for a fight whenever someone came near the tank, even to feed him
Overall great pets to have, would highly recommend to all!
