Lucy. I have care sheets that I printed out that each Betta customer gets. I also advise them that the small keepers are OK while the betta's are young but they must have something bigger as the fish grows.( this also brings them back to spend more money on tanks and equipment.

) I do have tanks they just don't show in the pictures.
MM yes I love these containers. They come in different sizes to so you can upgrade them as the fish grow out. I got them from a company that sells all sorts of containers. Here is there website
www.containerandpackaging.com The nice thing is they will send you free samples so you know exactly what you will get when you get ready to make an order. Do a search for plastic containers.
