hey i am new. sorry if this is in a wrong section but here it goes. i am a begginer fish tank owner. all i got are a couple of plants, 2 freshwater angels (my third one died), one otocinclus catfish (the other died) and a frog. does anyone have any recomendations on what types of fish or inverts i can put in their? (did i mention it was a freshwater tank?) i am thinking about a freshwater clam but i am not sure about anything else.
