Could have been from a pre-existing health issue, could have been stress... Sometimes it just happens. What were your water parameters? PH, Ammonia, etc...
Ph 7.6 ammonia 0 nitrate 0...i see to have an issue with female guppys dieing but never males and in the neon tank i havent tooken the ph i should tho but im slacking off and my ph test is running out so i have to go buy a new test kit:mad2:
okay well i currently have 10 neons and my pearl i am just worried that my 30 will be over stocked with 8 3 inch kuhli loaches a 5 inch male pearl and 15 1 inch neons...
psh us davids are just so cool. do you think i could throw a betta in there? he seems to have no aggression if anything he is a wimp in my 55 gallon and i had to take him out cuz the guppys where beating him up! i currently have java lace fern and i am planning to buy another light to put on the tank so i'd have around 1 watt per a gallon and i'll trim my java moss and throw some of it in there to.
