Should cucumber be blanched and deseeded before feeding to plecos?

Cucumbers do not need to be blanched before feeding to plecos, but blanching can soften them and make them easier for the fish to eat. Deseeding is generally not necessary, as plecos can handle the seeds without any issues. However, it's best to wash the cucumber thoroughly to remove any pesticides or contaminants before offering it to your fish. Providing a variety of vegetables, including cucumber, can contribute to a balanced diet for plecos.
