Hi guys, I'm putting a divider into my 20 gallon community tank that I am soon going to turn into a split Betta tank, I've done a lot of research, but my question is this. "OK, so I have the dividers in, but the Crochet Mesh I'm using is too soft, so it's sort of forming an S shape. View attachment 199358 it is creating small gapes on the area between the tank glass and divider sides, am I using the wrong mesh? I can't post a link to the site I'm using the tutorial off of because there are some not age appropriate places you can go from that page, ( View attachment 199359 I don't know why they have to stick that in there) But other then that it's a good tutorial." This is a quote from my other thread https://www.fishlore.com/fishforum/betta-fish/233056-changing-stock.html. I had to open a new thread because people who have answers to this question will not be looking in the thread named "Changing Stock." Anyway, if anyone has Ideas, that would be really great. Thank you!
