Hello. I have a 75 gallon with 1 pink gourami, 5 corys, 1 neon pink tetra, and 1 spotted pleco. They are all ďadoptedĒ.. I got the pleco a little under 2 years ago from someone who was going to ďset him freeĒ in a pond, in the winter, when he was only 3 inches long. The rest came from a dentist that was going to dump his fish in a parking lot and sell his aquarium. Itís a weird mix for sure and itís not the fish I would choose but itís the fish that have. They all have their parts of the tank they hang out in and live pretty harmoniously oddly enough. But I will be moving from an apt to a house next summer and then the pleco will have his own indoor pond so he can have room to grow into the big monster he will certainly become . Iím here to continue learning about proper aquarium and fish care. Iíve been lucky enough to have a stable tank, no injuries, and no illnesses in 6 years but Iím here to be prepared for when something does happen.
