must be my luck with silvers but i had 3 different silvers at 3 different times and all 3 have now died in my 29gal... the first 2 were maybe 2 inches and the latest one was around 4 inches that i just bought this past weekend. I'm new at keeping these fish and i know silvers espically are not as hardy as the other aros but i have a 2.5 inch jardini in another tank and he has been doing fine for the past month now. the first 2 were i think stressed out the most compared to the 4 incher but the big guy died earlier tonight. he was swimming fine and eating fine this morning when i left my house. i mainly fed him hikari food sticks and bloodworms as treats. the water params were i think ok.. no ammonia or nitrite present. nitrate was low but present. the water was hard and more alkaline.. i put some stress coat in when i first put him in the tank but none since then... i had an algae eater and a small pleco that i bought the same day as the aro in this tank. any ideas?
