I just got my betta fish and the filter I got was the Top Fin filter and they said I may need to get a different filter next month because these were on back order and she didn’t know if she could even get them for me. One little search on here and I found them! And definitely Big Bang for your buck!

Fit perfect in the filter and do the job .
