Hey all- So my problem is that every time I get new fish for my tanks, I have a huge problem getting the fish through the first week of having them. I have tried all different sorts of acclimation techniques and I still do not think I have bought a group of fish and had 100% survival. Most of the time its only like 50-60% survival rate. I have tried just floating the bag and letting them go, floating bag and then drip acclimation, and just drip acclimation and none have worked for me.
Today I picked up 7 neon tetras to add to my tank and I did 10 minutes of bag floating and then a 2 hour drip acclimation to double the amount of water. I put them in a quarantine tank with a cycled sponge filter and the quarantine med trio. I just went to check on them before going to bed and already had 1 little guy die on me.
Can anyone think of anything as to why I constantly have this issue. I feel like it isn't my store's fault because the fish always look healthy at the store and they are very reputable in my area.
Thanks for any help I can get!
Edit: Just wanted to add that I don't think its water parameters either. They are always tested before getting fish. Today that tank was 0 ammonia, 0 nitrite, 10 nitrate, 7.5 pH, 79 degrees F.
