I get taht red/orange/brown/rusty slime stuff on my walls/plant/heater in my tank and would like to get rid of that.
it's a 10 gallon tank, and it has 7 baby molly fry and an an albino cory catfish
How long have you had this tank? The "rusty" stuff (probably some form of algae) often accumulates on a tank that is relatively new and most likely still in the process of cycling. It goes away after a while, or you can simply wipe or scratch it off. Or, it could be just regular brown algae if your tank is mature (cycled). The algae eater that you choose should not be large because your tank is small. I think many people on this forum would recommend 2-3 Otos for you. Chickadee knows a lot about them.
thank you Isabella and Carol, approx. how much does one oto cost?
because 5 of my fish have gone missing in my tank...no bodies or any sign of them have shown,
and don't want sometime if it is expensive, expensive go missing in my tank.
+if you know why/how some of my fish have disapeared it'd be great to know!
algae needs light....... you may have your lights on to long during the day? your tank could be by a window getting its light from there? or it could just be cycling like others have said. take a scrubby pad, the kind used for doing your dishes or cleaning or whatever..... rinse it off real good... and clean your glass on your tank. then try and elimanate some of the light see if that helps.
