ADFs are fine with or without other froggy friends, but having them in fish tanks poses a problem for most people as far as getting them to eat properly. They are very slow to find food and often end up underweight and sometimes starving with fish competition.

Species only tanks for ADF are usually recommended because of this problem. ACF are notorious pigs and I have never seen a fish able to out eat my crew. Their size and hunger make them better at contending for food then their timid miniature counterparts.
