I have a 75 gallon tank that may soon be free as its current resident seems to be outgrowing it. I was thinking about CA cichlids. I have been hung up on what I really want to get out of the tank, however. I'm not sure if I want a single specimen, a pair or a community of smaller fishes. I really like Parachromis species, and would love a pair, but I've read too many varied accounts of whether a pair can get along long term. I would like to avoid having to use a divider as this is my main display tank. Other ideas I've tossed around are a pair of salvini, or a Thorichthys community with serpae tetras and/or swordtails. Then I get hung up on the fact that I like big fish.... I like the idea of live plants, but that's not a necessity (and I know quite pointless in many cases).
So, if you had a 75 gallon as a display, what would you do (single, pair, community, and what fishes) and why one vs another?
Also, as an aside, have any of you tried using quick-growing floating plants such as duckweed for algae control and supplemental nutrient control (not a replacement for WC of course...)? I could see it being quite useful, and adding a natural look to the tank both because of the cover, and the diffusion of light into the tank. I could also see it being a pain during WC's, or with filters. Just wondering...
