I'm getting a 45 gallon cage to house in my office. I was wondering how many thumbnails I could put in there (I'm thinking of getting imitators)? Is it too big for a thumbnail species? Are there any bigger frogs that would utilize the 45 gallon better (ones that won't stay on the bottow of the cage and waste the height)? How much of a threat is there of other females eating eggs in a cage that size? Any help would be great!
