too big ar.. sell me, i would like to have it. Used to have the same one last time, but tot of giving up tat time den sell it away. Regret now. PM me if u wan to sell.
actually let ur water leave overnight, say 24hrs in total. with a small powerhead or air pump to create some movements. It shld be sufficient. Oh, dun forget to add in anti-chloramine too.
sign of bullied by bigger fish? behaving abnormal? how long u got it? 3 sally will be able to finish a small chromis in a day i guess, plus other critters.
If it's totally new, it will need some days to break-in. If it's second hand, try using a 1500l/hr and above pump to drive it, tune the water level somewhere near to the neck, and not the recommended line. Hope this helps.
