is it always been the same food u feeding it with just this time is different kinda poop?
the poops determined by what it ate, and also could be use as digestive problem or health
hey mate.. like others have mentioned above the poop is usually the color of the food.. long time back.. when my aros used to be on feeders their poop was black.. and with hikari pellets it is brown.. at the same time look at the poop.. if it is like corks then it could be a water issue.. has happened quiet a few times with my aro. check your water parameters also and do a water change if required.. cheers..
off topic question but my arowana hasn't been eating lately! yesterday i did a waterchange thought it would help but it's the same, he wouldnt eat but he swims around normally, should i be concerned?
