Hi! Thank you for the reply, the tank footprint is 4’x2’x2’. Sadly I am not able to upgrade at the moment however I would love to! As for water quality I am fully willing to do extra water changes, currently I am changing a 100 gallons a week on that tank, however at the moment that’s not really true. I haven’t felt well so they have been missing water changes but I tested yesterday and the water is ok (0 ammonia, 0 nitrite, 60 -80 nitrate), not the best but I plan to water change today, but that’s all besides the point. Do you have any advice to get them eating? Thank you!
