I am soon ready to add new fish to my 27 gal tank. I have 5 zebra danios and would obviously like to keep those. I am looking for some fish with really bright colors, maybe a few small schools and some "centerpiece" fish? My pH is around 7.4-7.6 and the temp has been 74-76 consistently. Anyone have any ideas about what I can add? Here is my list of fish that interest me so far: Kuhli Loaches (I heard these actually get much bigger than I had expected?) African Dwarf Frog Betta African Cichlids (I know this is very broad, any specific suggestions?) Guppies Gouramis Pleco CoryCat Ghost Shrimp Tiger Barbs Killifish Any input would be greatly appreciated!! Thanks!
