Oto its a fish, google it out. If you got larger tank, then you can use SEA or CEA. But becareful SEA and CEA can gro pretty big, mine was around 4 inch. And sometime saw them mummble on my plant leave.

thank pal....actually i have that oto fish ....and some yamato shrimp.....
my aquarium pic....but sadly i have removed the red plant (forget the name)

sori bos..just saw your pm today.
ok, lets get straight to the point ...nobody can help you if you dont help yourself, you have itchy hands that you must put your hands into your tank each time you go near it, im sure you are overfeeding...common beginners mistake...how many time did you feed your fish per day?
fertilizers?...overdoze im sure.
keep your hands off the fertilizers until your plants have rooted..at least 3 weeks for the 1st dose.
your photo looks like hair algae but its greyish..is it that you have arleady added algae killer when you took those picture?
