Tank size is 75 and tank mates are 5 Discus, apistogramma sp., electic blue ram pair, cardinal tetras, GNP, panda corys, 5 striped kuhli loaches
Multiple pleco (meaning, more than 1) is always risky. They are territorial, some species moreso than others. If there are several good hiding spots in/under wood or rock and the tank is large enough, it usually is workable. Pleco like to find their own home, so having multiple suitable nooks and crannies even for one is always preferable. They will push and shove each other when they meet, but with enough distance between them they may
be fine. Of course, this depends too upon species. According to my info, the GNP is highly territorial to all benthic species, so this is one that is probably best on its own.
I have a Hypancistrus furunculus in my 5-foot 115g, and a Rineloricaria parva. The latter is very peaceful of course, and had been in the tank for almost 2 years before I acquired the H. furunculus. The newcomer selected "his" home in a crevice in a large chunk of bogwood about 2 days after being introduced to the tank. I was sitting observing things one day and the Whiptail was doing his normal thing, grazing over plants and wood, and happened to come to the crevice where the H. furunculus was sitting. The Whiptail nosed in, the Hypancistrus did a little "shake," the Whiptail nosed in again, the Hypancistrus did a slightly larger "shake," and that was it. The Whiptail very quickly backed off, went around, and has never since (when I've been watching anyway) ventured close to that spot. They come out at feeding time and seem to not pay attention to each other. The Hypancistrus is also a very peaceful species, but this little episode illustrates that the fish is serious, and other loricariids know it. Two Hypancistrus however would be something of a different situation. These are often stronger when one fish has been in the tank for a time, as it regards the entire space as "territory" to be defended.
It's too bad you have the GNP. Farlowella in that tank with discus, cardinals, etc. would be absolutely ideal. The perfect match.
