Hi, so about six months ago a friend gave my 1 1/2 year old a setup that included a african dwarf frog. I've done some research and find alot of different opinions on many things. right now he is in a 30gal tank with half sand and half rocks. I've heard to use sand since its softer on their bellies but then i hear not to use it. so far no issues with him eating the sand, so is it okay? also when we got him i did not know what to feed him so the guy at the fish store said bloodworms, so i've been feeding him live bloodworms and i just put them in the tank and he eats when he wants to. i read not to do this but its worked for over 6 months do you think its okay? i also read somewhere not to feed them live bloodworms, what are your thoughts? he seems to enjoy them alot. can i also feed him live brine shrimp instead of frozen? my daughter loves this frog so i want to do whats best for him, he seems very happy in his tank, but should i add more frogs or some other companion? any advise would be helpful, thank you =) i would normally have done all the research before getting the animal, but like i said the hubby had a friend that stopped by with a tank setup while i was at work so this was a surprise but we are happy with our little froggie.
