Just sharing my recent experience with you before you commit to ADFs. I already had a pair in small cube tank. I put them in with my male Betta in his 10 gallon tank. They all seemed to get along for a couple of days, then I noticed Azure's fins looking ragged, and him being withdrawn. This morning, I saw one of the frogs grab his fins and shake him like a ragdoll. No more frogs in the tank for me. Azure's too important. All frogs may not be this way, but mine were, and I won't risk tankmates again.
