{"title":"Nano Fish","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eNano fish are the smallest schooling fish in the aquarium hobby, perfect for nano tanks, planted aquascapes, and shrimp setups.

Be aware that almost any fish will eat shrimplets (baby shrimp) if it can fit them in its mouth, so a heavily planted tank with moss and cover is essential if you want shrimp to breed alongside fish. For a dedicated breeding colony, a shrimp-only tank is still safest.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eNano fish are ideal for aquascapers and nano-tank keepers who want active movement and color without the bioload or aggression of larger fish.
