Heya mr pleco mine mosey on out at anytime.. they love courgette but they mainly love meaty products, they get frozen cichlid mix, pleco tabs they seem to mow down, but I do notice they go nuts on mysis shrimp cubes, will hoe down any flake or spirulina that hits the bottom. But they frenzy out on the frozen cichlid mix the most which has krill base, spinach, etc
