Its no suprise to find these tiny critters on live aquatic plants at pet stores. However, if your culture is running kinda low ( and forgot to make backup cultures LOL ) for your newly free-swimming fry I found a lil great thing :) On my journey to the Petsmart the other day I picked up a Marimo Moss Ball Plant for $8. It comes in a betta container with a green lid. It is literally PACKED with TONS of infusoria! I set it on my window in the sun still in its original water and moooooorrrreeeeee!!!! o.0 like I really REALLY cant stretch how much are in there! Its ridiculous....sooooooo many.....I havnt seen so many in my own lettuce/grass cultures!!!
so for those who dont like DIY cultures or hate ordering cultures online, a few of these things should help you for that first week of first fry foods :T If you need some fast- this really comes in handy! Also I picked the one with the greenest looking water if that helps.
I just wanted to share my experience with everyone because this info might help people out :) I hope this was helpfuł
