I have a 10 gallon tank, I have had it since the beginning of January, so nearly 2 months? I have 6 black neon tetras and 3 skirted tetras (2 black, 1 white) and 2 shrimp. I feed them Wardley Total Color twice a day and Hikari freeze dried bloodworms twice a day as well. Ok now for my question. It seems to me my tetras used to go up to the surface and eat their flakes, but now they just hang out in the middle section waiting for the food to be dumped under by the filter. Is this normal? I feel like its not, are they being lazy?
