Yeah, his posts have really been irriating me lately. Get him out of here. I am worried some one who doesn't know better will think he knows his stuff and will follow his advice.
1) Do not use motor oil in your tank!
2) MoJo likes jokes, take his advice with a grain of salt ...
3) fruit is part of many fish's natural diet and in small portions a healthy treat. However, do not feed too much. The digestive system of aquarium-kept fish is not used to it, and it could result in an upset stomach.
It will eat just about anything. Try peas as for motor oil well if its that good to tell that to the wild life when the Exon Valdese went down its still haveing an impact now
