APPROXIMATELY 20 pieces. Oak leaves contain tannins and have the ability to slightly lower ph. A great food for shrimps.
These leaves are one of my favorite leaves to use. My shrimp love to graze on the bio-film that collects on these!
nice long lasting.....great for shrimp tanks
These leaves are a good size for shrimp tanks. It's so convenient to just take them out of the bag and not worry about if your wild collected ones are free from bacteria or toxins.
I'm not sure what I expected - but these are just oak leaves. They are smaller than the oak we have locally so work well in nano tanks. The biggest advantage of these over self collecting is that they come from pesticide free trees. Many areas are subject to agricultural drift of pesticides or are in manicured areas where the roots pick up chemicals sprayed on the ground cover or lawns. Shrimp are so very susceptible to pesticides that paying for oak leaves is worth the peace of mind.
Got these as a third type ofleaf to use as leaf litter in all of my tanks.
