zerojquan85;4227614; said:If you keep arowana like i do.. Glass is certainly not a good idea.. I've since and witness first hand myself of the power and effects Arowana's can do.. they freak easily and they jump.. If you have a glass lid.. and its not as durable as Acrylic.. they will crack... I've see too many threads on MFK from members who have glass lids and other weights to weight down the lid.. that actually caused a major disaster as the arowana jumped.. not only cracked the lid.. but the weight on top of the glass fell into the tank and cracked the bottom glass...
I would say that if you have fish that are peaceful and aren't jumpers.. use glass lids... Otherwise.. Acrylic is a MUST for any aggressive and belligerent fish..
Appears i will be having to check out the acryllic tops next week at home depot... Any suggested thickness for a 6x2x2 180??
