:help: Has anybody noticed their Clown loaches reacting to liquid plant ferts? I'm actually not even sure that's the cause but it seems like everytime I do a water change and add the Flourish, they will sometimes flash on this big centrepiece in the tank. I've actually treated the tank with API General Cure on several occasions and everything seemed fine and then 3 or 4 days later and it starts all over again. There's no visible signs of disease or parasites and believe me i've been checking. Water parameters are fine and the tank is well established for over 4 years. Tank mates are 7 albino cories, 2 rubberlip plecos and a 2" rainbow shark. The tank is 60g plus. I would be grateful for any advice...Thanks
