Hi asking for peoples experience in keeping more than one FH together with other fish. My 210 is up and running with a large sump 6 times changer over rate with two canisters separate for pure carbon and a back up in case. Temps at 26 c / 78 f. There are two tiger oscars 7 + 8 " and now a Thai silk flower horn. An Asian aro is on route in 3 weeks. The question is can you keep more than 1 silk, is it better to have 4 than two ( stop a Mexican stand of). I understand there's alot of paticular fish personality to consider. Thanks in advance
