Hi i have a 450L 5F tank started with 4 oscars trying to get a pear but now i have got rid of the other 3 thay where not working out now only left with one at 21cm now so looking for a new tank mate was thinking of a jd or a jaguar cichlid what do u think. Have a fx5 and a ehime 2229 wet/dry. also have 2 convicts and a tiger pleco in there.
