no worries I can understand that
I would personally keep some dwarf snakeheads and try and get a pair
Channa Orientalis or Channa Pulchra make intersting tank mates, classed as oddballs extre,ely easy to keep eat anything and aren;t delicate
or try a brackish tank... just need salt mix and a hydrometer to measure salinity and you could keep puffers or knight gobies, waspfish etc
have a good trawl through this site and I;m sure you;ll get some ideas. I;ll think of some others bit tired at the moment heads not thinking straight lol
