75 gallon tank

    I'm rethinking this Oscar thing as they do have a really big bioload for a 75 so I decided to go with a different cichlid type. I know for sure I want a a black ghost knife and 4 silver dollars sone cichlid types I like are Jack Dempseys, Green Terror, Green Texas Cichlid, Severum, Firemouths. I just want opinions on which of these cichlids will go best with the fish mentioned above.

    the ghost knife may hide for a good amount of the day and you may not see him much. just letting you know:) also i would add a few more silver dollars. make it al least 6 as they like to school. i dont know much about green texas cichlids. i do know that jack dempseys and green terrors will probaby bully and possibly kill silver dollars and maybe the knife. a fire mouth or 2 could work well. a severum would fit in the tank. i dont know if they would be compatible with the others. how about u get:

    the ghost knife
    6 silver dollars(maybe more if you get really really good filtration)
    and 1 or 2 firemouths

    just know that beween cichlids and the silver dollars, you will not have live plants. if you add them they will be eliminated...

    Really I have heard jacks and silver dollars make great tank mates would a severum pair, 5 silver dollars, 1 ghost knife, work the filtration is a marineland 350 and a emperor 400. But also with the severums does it matter if they are different colors.

    Silver dollars are very shy fish that spook easily and require more than a 4ft tank. They can run into the glass and injure themselves.

    I'm don't know a lot about the other fish you suggested, but I think you could do a pair of jack dempseys in a 75g.

    I really would like a single severum, firemouth, some amazon type dither fish with a ghost knife

    Hey josh7 - any of the fish you mentioned have a huge bioload. In general, all carniverous fish have a higher bioload than "regular" fish. The size of the fish contributes to this as well, but remember when choosing any of a JD or GT that you will have to consider the same bioload issue.

    You know I think I'm gonna drop the ghost knife as they seem to get very large can I have a mated pair of jack dempseys with a featherfin squeaker or is that gonna be an issue.
