I just setup my 50ltr 80x25x25 recently with some lampeyes, two female guppies, a couple of female fighters, a clown and some little BN. Also have a 60x30 planted rimless with only my Salamander PK in there but he can be moved if need be. I could take the guppies and put them in the rimless planted (minus the fighter) but chuck some lids on it for security. Not sure where I could put the shark without setting up the 80ltr.
