So I plan on adding some fairy wrasses to my current build and of course want to put each one in a qt for a minimum of 4 weeks. Since they seem to sleep in a sand bed and I have a ton of extra sand, is there any harm in having a sand bed in a qt with just pvc as hidding spots other than rendering the sand useless after qt? I've seen people use a small Tupperware container of sand but figured if I got the extra sand why not use it.
Thanks in advance!!
