Do u use a filter? if not, thats one reason ur fish got sick.
Did u let the water sit for a couple days before u put ur fish in it? thats another reason for the fish dying so quickly, it was in shock & weak so the illness won with ease.
DO u have a heater? if so, is it too high? if so that can make sick very ill & cause fin rot or ick or just kill them.

If ur willing to spend money on the fish to keep them alive, use this stuff



This is AWESOME stuff!!!!

Ever now & then Mango get ick. He get into everything & hurts himself & gets ick on his chin. I treat him only once & its gone for months, unless Mango gets into something else, stupid angry fish.

I treat my feeder goldfish with this stuff before I put them in the pond, other wise they will all die with in an hour. I cannot treat the pond cause that'll harm Axles shell, but just treating the fish for an hour is safe.

This stuff cost me under $10.00 & its almost 2 years old
Also my tanks and fish are MASSIVE compared to ur wee fishies.

Oscar is a foot long, Mango is almost a foot long & Jack is 6 inches ling. Mango's tank is 30 gallong & Oscar's & Jacks tank is 55 gallons.
I let the water sit for just about 3 days, I use a small small filter, no heating lamp though. Thanks for the suggestions I will try them with my new fishy!
