Need help with new ACFs
last week I moved a few african claw frogs into a 30 gallon tank with some goldfish. Before anybody shuns me, please understand that I'm fully aware of the risks I'm taking. I've heard of some people not having conflicts between the two, and some frogs killing the fish. So far, my frogs haven't been too aggressive with the fish at all. Tomorrow is the first tank cleaning day and I have a few questions. Should I even bother cleaning this current gravel, or should I get larger stones? I heard it's possible the frogs could accidentally eat them. Also, do you guys recommend any certain plants I should add? They seem to like the couple I have in there right now but I want to get rid of the couple fake ones I have. Lastly, can you tell if the frog in the last pictures is female yet, or are they too young?
if the attachments don't work I will re attach
