My two did, once I saw the pic they looked exactly the same. They get BIG, not apple snail big, but fairly close. My son had two in his 5 gallon and they ended up being the size of his fists (he was 11 yrs old), eventually became Fahaka puffer treats. They do eat plants occasionally, but his avoided Riccia for some odd reason.
