I have a 125 setup with fluval fx5 and hob filter... In the tank was 18" silver arawana (dead now), 2 18" tiger shovelnose, 2 12" oscars, 18" clown knife..and 18" pleco...did about 25% water change and had an ammonia spike...lost my arawana ..ever since I've checked perimeters and they are all high...quit feeding cause they weren't eating and breathing heavy..then my tiger got hungry and tried to eat clown knife..now my knife fish is beat up and the perimeters are going crazy now they r all high..what do u recommend..knife fish is struggling and bad water is not going to help...my tank has been setup for over a year..
