ok so my 2.5 betta tank was really algea-y and i decided to buy a cheap gold mystery snail. i found out how cool they are and i cherished it. then it disappeared! theres an internal filter in there and i redid the water and he crawled in there but i managed to take him out so i could see him and theres no way he couldve been killed by that because hes not neraly small enough to fit in the ouput hole. also if im correct bettas ignore snails (well at least mine did). hes not behind and bushes i checked all around he didnt fall out and theres no way my betta couldve eatin him in one day! WHERE IS HE!>!?
