I have two Empty Aquarium, a Bagged Swordtail Fish, and a Bagged Guppy in my inventory, on the two fish items there is a 'Special Use' option to give them a place to live, but it doesn't work. The items still remain thankfully, but I get a blank page with url https://subeta.net/item.php?act=custom&itemid=4123498475 and https://subeta.net/item.php?act=custom&itemid=4123498403 after clicking.

Still not working. Thank you.
