Who is a better tank mate for an african dwarf frog? betta or snail

I have a betta, Twilight, in a 5 gallon tank. He was aggressive toward one of my snails so he is by himself now. I have another tank, 2.5 gallon, with now 4 mystery snails. So I don't know which would be the better tank.

The fourth snail is a Petco rescue attempt. I bought him today with the frog because when I checked him out myself, despite the fact everyone else was dead. His body wasn't outside his shell and I could not move his cover. Since I broght him home an hour ago his cover has moved slightly, as if to bring in air but no other movement. The cover was shut tight when I put him in the tank.

I currently have the frog in a small critter carrier with an air hose, food, and a couple of fish ornaments to climb on to reach the top.

I'd prefer to put him with the snails because they don't eat the food that falls to the bottom and he supposedly does. I feed the snail betta pellets, so they eat at the top of the water line.

So should I put him with my betta or my snails?

 

I've never tried it but I've heard hit or miss on ADF's with bettas. Keep a close eye on them and be prepared to separate if need be.
I don't know that much about snails, but don't mystery snails grow rather large?
If they carry a heavy bio-load that probably wouldn't be a good fit for the ADF.

 

I am going to try the frog in with the snails right now. Just to see how it does for a day or two. But I will keep that in mind.

 

Keep a close eye on the parameters and good luck!

 

From memory, I think someone said mystery snails need 2.5G per snail... But It might be wrong.

 

The 3 were getting along fine. I only bought the fourth because I didn't want it to die.
