If it were me, I would get a large school of pygmy cories or kuhli loaches, and perhaps a large peaceful school of fish like zebra danios or similar.
ADFs are pretty difficult to manage in the aquarium--they are nearly blind and hunt for food by smell. This means if you drop the food in, all the other fish are going to get it before the frogs even realize what's going on. When I had an ADF, I had to put my whole arm in the tank and dangle a live blackworm in front of the frog's nose for 30 seconds until he jumped up and got it. ADFs also like to be in groups.
Im going to have to disagree on it being a common pleco. It looks a lot like an L96 or L160:
But I am not an expert when it comes to matching pleco pictures to their L numbers.
I strongly suggest not getting anymore plecos or catfish. Cory's would be the exception. Some pleco's DO get incredibly large but this can take many many years. My common pleco is finally 8 inches after having him for 7 years. Who knows how old he really is? I had him in my 35 gallon for 5 years. Many cory's went in and out of that tank with no problems. I also discourage putting in the african clawed frog. I literally watched my frog attack one of my neon tetras and swallow it. I wonder where the other 3 went? My frog got mega fat after they disappeared so I gave him to my girlfriend. (Who also lost her neon tetras with no trace of where they went. Did not found them on her floor or in the filter). I like these frogs but I dont like losing fish to inverts!
6+ Cory's sounds great. They love large groups. Since I am new to betta care all I can say is make sure any fish you get are the same size as it or bigger. My last betta loved to bully my little rasboras. I thought having them in a group of 5 would keep some aggression away but it really didnt. The betta stressed them out bad!
Hope I could have helped some. Good luck.
