Hello SA and welcome to FF! Also a fish keeper with 50 years experience in FW and SW, mostly breeding SA & CA cichlids. Last year I got my first frog and after a break due to health reasons got me another one couple months ago. From reading your post can see you are still undecided so maybe want to take a look at these articles before taking the plunge. First this one to see if any species attracts you more than others: Frog Forum - Choosing a Frog . Then since you mentioned Grey's take a look at this one: Frog Forum - Gray Tree Frog Care and Breeding . For aquatics like ADF or the larger ACF this is good reading: http://www.frogforum.net/care-sheet-...warf-frog.html.

Mixing frogs and fish is a risky endeavor because they prey on each other and share many parasites which could get your frogs sick. Both ADF and the larger ACF do prefer zero to little current. What I've read some members do, is point the canister filter spraybar to glass wall and minimize currents that way. Be aware that both species require around 10-12 in. of max. water level above substrate so your filter needs to be able to handle that if in a tall tank.

IRT Clown Plecos (great little fish) maybe it will work with the ADF but not the ACF; which will grow large enough to try and eat a Clown Pleco with disastrous results for both. Plants will be fine with both aquatic species and if plants grow to top they will climb above them and hang around the leaf canopy.

Hope this info helps! I find frogs similar to fish and there are all kinds of them with very interesting behaviors and attitudes. Have a nice week !
