So i was reading in some of the stickies and it was saying that you should use non silica sand, which im ok with because i really like the sand look but was curious what brand you guys use or type, as i use the target brand sand in my fw tank but have heard its mostly silica. Question two is that i have come across a good deal, a couple of small teacups for 25$, hes also selling some small motoros for 80$, im totally ok with spending the extra if its a better choice for a newb. Question 3 is would a royal clown knife be a good tankmate? Im building a 4X4X1.5 tank (there will be a guard rail around the upper edge as i have read a few forums on thinking 18 being a minimum and 24 better, so the glass i had is 18 so i figured better safe then sorry. Thanks! (i know the knife will eventually need a bigger tank but its an excuse to give my wife that i absolutely have to go bigger )
