Hi Soyadude

....I think for snail problem...you could consider of putting mini puffer as mentioned by Dom....i placed a mini puffer in my 2ft planted tank and it is very nice to see the mini puffer in action...haha he would slowly search and destroy the snails.....so far in about 3-4 days ....all snails seems to disappear ald.......the best part for me is...the puffer didnt touch or go near my yamatos.......so maybe you could try it....

regards,
Gary
