i have a 30 gal well planted aquarium. it has 6 cardinal teta, 6 penguin tetra, 2 ram cichlids and 4 amono shrimp. im quite sure my platys have just had some babys. my rams are chasing the fry. does this mean they are the rams babys or isn it normal. also if you can give me some tips on raising the fry that would be great.
