I recently completed a fish-less cycle of 30 days. I tested the water during the process and was pleased with the results that remained through the last test on Saturday Night. This past Friday was the end of the 30 days and Saturday I purchased 4 Neon Tetras and allowed the packing water to sit in the tank for 20 minutes before releasing them into the tank. Particulars- the tank is 30 gal, with plants that have been in for 2 weeks , accompanied by some large stones and hardwood roots . The Tetras redefined active... they were all over that tank inspecting every crook, rock, plant and submerged wood. When I fed them Saturday evening they raced about the tank eating like there was not tomorrow. I noticed this morning, when I fed them... they were not as aggressive toward eating as they were before. I did not have much time to observe them so when I arrived home from work this evening... I fed them again and watched them closely. They would move up on food flakes and then swim away as if they were looking for something different. They inspected much of what I fed them but they did not eat as before. To you more experienced Fish-Keepers what may be the cause of this behavior?
