I have a 55g with 4 fish in it they are as followed a 5 inch 4lined-cat,10 inch pleco, 3inch rainbow shark and a 2inch honey groumie and I want to get three more honey groumies and one more rainbow and I also wanna get a pictus cat will that work
yup, sounds good to me. but in the future u might want to get a bit of a bigger tank. plecos can get to be over a foot and a half, so just keep that in mind.
the gouramis might fight each other
the rainbows are highly territirial and need their own "space"
the pictus will also need its own cave or territory.
