Hi Bro,
Glad the fish is doing well... Yes it needs a mate... and if it pairs up, u can start breeding nemos
I saw your post in another thread. The 2 feet cube is a good buy! go for it!
its an internal skimmer...if your 24cm cube tank is going to be converted into a sump, yes it fits in.
I think you drop by would be better coz my camera is spoilt just 2 weeks best, but let me know fast!
