I recently got a school of 9 Neon Tetras to go with my 2 quarter-sized Angelfish. In the past few weeks, the Angels have started to become more aggressive at feeding time and constantly wait near the surface until they see my hand. The Tetras all stay on the other side of the tank, with the filter (the Angels don't prefer the current) so they rarely come out to the surface. What is the best way I could feed the Tetras? Every time I put some food on the other side of the tank for the Neons, the Angelfish dart over there and eat the food. It has been a couple days... I need some recommendations for feeding Neons!
