[I have a 10 gallon FW thank that only has (1) platy and a plecostamus in it that I plan on keeping. Isn't there a way to convert or acclimate a platy to saltwater? If so, does anyone know how to do this? I would like to convert that fish to saltwater so that I can use my 10 gallon for a QT tank. Anyone have any advice? I have to add salt when I do water changes for my platy anyway. Thanks for any and all help!! ]
