What can kill small fish like guppies but not big fish like barbs and tetras?
Here's my problem: I bought a dozen fancy guppies and put them in my main tank skipping the QT process. I already had dozen in the main tank, but I needed more females. Well Today *Sunday* I lost another one stuck to the filter. I also lost another one yesterday with the same result and one of the new ones the day after I got them. I did 25% PWC yesterday just to be on the safe side.
I did a test on the tank today.
Ammonia: 0
Nitrite: 0
Nitrates: around 5
Tank size is a 44 Gallon and with 20 guppies in the tank. It barely puts a bioload on there. I assure you its cycled but it could be in a mini-cycle because of the new fish and the grav-vac I did the day before I bought the fish.
I have cory cats in my 44 gallon and my sister's 10 gallon.
The tiger barbs and black skirt tetras are in the 10.
But whatever is killing my guppies is not killing the cories or the barbs and tetras.
I'm thinking theres some sort of poisoning in the 44 gallon that could be coming from my watersupply?
What are the types of poisoning out there besides ammonia, nitrite, and nitrates?
Thanks
