i noticed yesterday that there is quite a lot of tiny white worms about a mm in length and thin as hair not only riggling on the glass but in the water aswell. current stock in the tank is two 12+' jaguar cichlids. the tank is only a few weeks old and bought brand new. i did a 60% wc today and added a 6% plec wich seems to be eating them off the glass. should i keep doing large daily wc or is there a treatment out there i can buy?
