If you find yourself with an unwanted pleco fish, there are several things you can do to ensure its safety and well-being. The first step is to make sure that they have a healthy environment. Plecos need at least 50 gallons of water for their tank, as well as ample hiding places, such as caves or logs. Additionally, make sure the water parameters are correct for this species – a pH between 6.5 and 7.0 with temperatures around 73-80 degrees Fahrenheit (23-26 °C). Secondly, provide your fish with plenty of food options including algae wafers, cucumber slices and zucchini rounds in addition to other commercial foods specifically formulated for plecos like Spirulina tablets or shrimp pellets. Lastly, keep in mind that these fish will outgrow their tanks quickly so it’s important to plan ahead by either rehoming them or upgrading their aquariums accordingly once they reach full adult size – usually within 12 months from birth!
