Hi All
My A. agassiz alenquer produced a lovely cloud of fry (40+) on 16 March and they seemed to be doing a great job, with minimal parental aggression, then suddnely 6 days post free swimming I noticed that there were only a small number of fry, and i could even see a dead one floating in the water, the next day they were all gone.
I have no idea why ?
Thoughts to date are father ate them or they starved or something was wrong with the water ?
Temp 26C
Water is pure rainwater, hardness measures at about 20ppm, I dont have the pH but it will be on the acidic side (too low??)
The tank is a 60cm x 30 x30 and the only fish in it are the aggies. There was no obvious aggression between the male and female apart from a little tail waving. The tank is only about 2 months old, small sponge filter, about 50 litres and I do 20% water changes twice a week. There is some leaf litter and drift wood and a few plants not as much as I would like. I was feeding some decapsulated brine shrimp eggs but not daily as well as small sinking food for the adults. In the past the baenschi fry I have raised, just seemed to have thrived on picking at the micro organisms in their tank and havent required huge amounts of additional feeding.
Any thoughts/advice would be really appreciated.
The tank next door now has some free swimming panduro fry as of yesterday, so I would like to avoid repeating any mistakes if I can.
Thanks Steph
