i gave plecos, ripsaw cat, baby bullhead and syno cats along with yoyo and clown loaches and (a large cana apple snail in a refugium). i had to move a clown from the other tank (leaking)which broke out in ich. so far only 3 clowns have ich but i cannot move them to treat bc i dont have any room for more tanks. ive used malachite (spelling) green before on cats but how does it do on loaches and snails? anything else availible? i can raise the temp but im afraid to salt bc im raising multiple sp of snails in a refugium for food. dont want to wipe out 1000s of snails. what are my options
