* Common Plecostomus (Hypostomus plecostomus): These are a popular aquarium fish and are tropical, needing warm water temperatures (75-82°F).
* Other plecos: There are many different pleco species, and some are more tolerant of cooler water than others.
* "Suckermouth" Catfish: This term is sometimes used for a variety of catfish that have sucker-like mouths, but aren't necessarily plecos. These can come from various climates, so it's important to research the specific species you are interested in.
To be safe, always research the specific suckerfish species you're considering to determine their ideal water temperature range.
