Depending on the size, you can probably do two fuzzies at a time (at least). If you want, you can also move him to every 5 days instead of 7 for a while. If you do increase his feedings to 5 days you'll want to slow it back down at some point. I use 500g as my break point, but other people use other numbers. The important thing is to bring it back to 7 when he starts getting bigger.
