Hello I have a 90G FW aquarium that was originally only housing a 8" goldfish and a 9" sailfin pleco. Recently we added a pictus catfish (4"), a tinfoil bard (9") and a silver dollar (5"). We were looking into what other fish we could add but I'm a little lost as most of my fish seem pretty peaceful...except the goldfish was picking at the tinfoil bard a bit at first (but now they are buds and all 3 swimmers seem to have made their own weird looking school).
My question is, what fish would be appropriate to add? we were looking at discus but i'm a little concerned they are a little too peaceful... but also seem very similar to the silver dollar to seems very happy. We were also considering a Hammers Cobalt Blue Lobster.... not too sure what to expect with them.
I know it may be a little weird but I get attached to my fish, especially my goldfish since I have had him for 6 years so I really want to make sure everything is ok.
Thanks
