SunGrow Mineral Rocks for Betta, Provides Hideout and Breeding Spot, Aids in Lowering Stress Level of Fish, 3-6 pcs per pack

I ordered these Mineral Rocks to put in my Shrimp nono tank. I'm a little disappointed that it is such a small bag. They definitely want you to keep ordering them. It says that this small bag will work for 3 months in a 14 gal tank. So since my shrimp tank is only 3.5 gal, I should get a few uses out of this tiny bag. This is supposed to help keep their exoskeleton in good shape as they need a calcium supplement in an aquarium environment. I may even put a couple in my Betta Toshi's 5 gal tank, that's only after I research it first. Don't want to hurt my handsome Betta Toshi.

My snail n shrimp never use these. I have tourmaline balls and they are always piled on them. Do they do something I can’t see? Maybe? I know they’re really ugly in my tanks. Wouldn’t buy again.

Careful this will Bring up the ph level in your aquarium! But if that's your goal this should work good!

Ok

Beta & snails loved them!

Bella la idea para mis peces

My betta.

This is what I received. Very dissatisfied with the purchase because nowhere does it mention a betta fish in what I received. I should have read the reviews below but its too late now. If you're a newbie to having a betta fish as myself and you are reading the reviews DONT WASTE YOUR MONEY and don't put your fish at risk. Such a disappointment

My goldfish and shrimps seem to be more active since using these. Very noticeable difference in fish attitude after 3-5 days of use.

Got it for our shrimps and they were instantly interested in it. Now, a few weeks later, there's rarely any sitting on it but the rock is still nice and clean so they might be on it at night.

Complete waste of time. Ive a shrimp only tank with easily 90 neo shrimp. I have soft water and conscious of molting issues. Put these rocks in am have yet to see any of the shrimp take interest.

The shrimp are not even remotely interested in these. Thankfully they were cheap lol.
