Hi Paul - cheers for checking in ... hope all is well - how is your tank doing?
Wow it's been a while since I cruised the sanctuary.Cheers - tangs love to swim & the bigger the tank the better - I'm not a member of the tang police, and I don't disagree with the fact they need lots of room to swim, mine is small, seemingly happy, well fed and healthy, has been that way for years.
This pic shows... he has quite a bit of room to swim & my scape allows for him to make laps behind the rock.
Bought some Hanna checkers today - going give them a go, I hate testing & these look easy - lots of vids on them ...
