Yes, Feeding once a week should be the minimum:yo:. When I 1st got mine, it was about 3" in size and i fed it every friday. I noticed during the week, the tentacles would change profile. Tues-Fri it would be long and stringy, Sat-Mon it would have its signature bulb shaped tentacles. Then i started feeding it 2x a week and it seems to keep its bulb shape tentacles, rich color with white highlights in the center, and fast growth! Iv had mine for 3 months now and its about 5-6 inches across fully opened! As for the clowns, they will host it if they feel like. Its one of those "You can bring a horse to water but you cant get it to drink" kind of thing.... I bought my Rbta for them to host it, but they find my leather toadstools more entertaining.
