Hey guys, thanks for your advice so far, much appreciated.
Sharn – good question, planted or barebottom tank? I would go for a planted tank as it looks more natural but will prepare to strip it bare if it’s getting messy. Yes, extra water changes, thanks for reminding me. :-?
Ron – what’s their growth rate? In a planted tank, water changes 3 times a week, feed twice daily and weekly treat of live feed. I would like to gauge how long I could keep them in the tank (6 x 6cm) before I need to upgrade to a bigger tank.
