Down to 3,Rasboras and Danios

fishyinpa

So I posted before how i was losing my danios like flies. Well I am down to 3 of them. Also down to 3 of my rasboras. I dont know whats killing them. I am guessing NTD,but I dont really know. Strange though,my neon tetras are fine. I only lost 2 since Ive had them. I havent lost any of the pencilfish. Wondering if its bad stock?

I did get the danios from several different places,but most likely the same supplier. The rasboras came from two diff stores,but again same supplier probably. I had 4 young rasboras who were fine for the longest time, I added 3 adults and they were gone fast! Do older rasboras kill off each other? Wondering if thats the case for them.

The rasboras are in a 14 gallon with 7 julii corys,cycled of course. The danios are in a 38 gallon with 10 pepppered corys, (lost one recently). Cycled as well.

I don't know if harlequin rasboras kill each other...i doubt it. I know that older rasbora espeis do not kill each other, at least not in my experience with them. I had a few older ones, added some younger ones, and they all get along fine. Wish i could be of more help

Have you checked water parameters? Ammonia, nitrite, nitrate; plus pH. B.
