how big is your tank? how big is FH? good luck.....
o yea... no live, frozen food all the way!! also hikari pellets are really good.. i use massivore and my Texas has the best colors ever....
btw i'd say get rid of the oscar but it should happen naturally soon enough....
about 6 inches, a 40 gal....whats up with the sarcasim Gasha? u got a problem? should i not keep them together? since u know so much pleaase enlighten me...
guess my sarcasm was explained.... that FH is all ready big enough to "F" some "S" up... like your oscar(looks alot bigger) at his size wouldn't stand a chance right now.... but all fish have different personalities so thats why i said good luck... i don't like oscars and was cracking a joke that your FH will kill it soon enough(i don't support fish fighting, just saying what could/probably will happen)
in a big tank i would say your combo depends on personality(some will just kill to kill) but you going to have some territorial issues on your hands most definitely with that size tank!! if you value your dempsey and oscars life i would make some changes....
