Hmm, that makes me question my guppy, I have one female that just wouldn't die ( not like I tried to kill her ) when I first setup the 20gallon the other month and didnt know about liquid test kits or the fishless cycle I had a round of neons die, male guppies eaten by my 2 pictus I had at the time, striped raphael died, Colombian sharks (wah) but she lived through it all. I got 6 good looking males the other week and they've been chilling in the 20g alone. Girlfriend caught the two albino cory and put them in the tank already and whenever I catch a Kuhli loach I put it in the tank since they keep getting sucked into my canister filters <.<
Long story short, I threw the female in the tank ( I know, instead of a 2:1 ratio I did 1:6 ) and instantly the biggest guppy which I consider the Alpha of their group started displaying and chasing away all the other males. After about 3 hours or so they aren't chasing her anymore but I would like to get some fry and see the results. I wanna make sure she gets pregnant but I dont wanna kill her from stress
