Ive only been keeping asian aros for a bit over 20 years, so boydo has 100 years of experience? Wow, Boydo's pretty old. I've stayed at asian aro farms down in malay for 3 years a few years back, i think i know what im saying. Im not saying Im better than Boydo or anything as maybe im not. There might be stuff he knows that i dont and vice versa. I never said 86 degrees IS too hot, i said it MIGHT be too hot. And its a proven fact that if you raise the temp, the matabolism rises and cuases aros to swim more actively and faster. One more ram into the glass could potentially kill it especially if he hits it harder than last time. BTW, having a sump on the tank means nothing. Having a sump could still mean you have unclean water or have horrible filtration.
