yesterday i set up a small 5 gallon tank with a mini filter and added 30 very very small feeders (guppies?) i thought it would make it easier then going back every week.. (i know that feeders can carry diseases so i dont want to get yelled at
).. i also feed the oscars and hampala shark ..krill and cichlid pellets.. but from my tank it smells like "fish" never noticed it before today.. would it be the feeder tank underneath or could it be my fish... sorry if this is a weird post.. but family isnt to happy about the smell.. any tips or advice.. am i doing something wrong...? any advice will help! thanks
