Re: Mantellas in general
I still have my eight crocea. I have had problems with tadpoles not thriving and slowly wasting away. The last time I had four successful froglets morph out, I kept the water well aerated, almond leaves, and a varied tadpole diet. I used salvinia for keeping the tank clean.
The last few seasons I wasn't serious about crocea though since I was swamped with pulchra and mad tads. The goal this year is to produce crocea and ebenaui before mads.
It's a given that the mads will reproduce. I usually can't stop them!
