hello and welcome ?
would you be able to post pictures when you get the tank,sounds lovely.
what sort of fish would you like to keep. ?
the comet,i'm presuming is a goldfish,and he would fair better in another tank,the
warm temperatures are not too good for him,and he can have the weather loach as company.
decor,depending on what fish you keep really
rocks for mabuna cichlids
planted with rocks,mopani/bog wood for the bnp to munch on,gravel/sand
gosh there's so much to be had.
