напиши информацию о тропических рыбах и дельфинах кратко на английском языке

Here is a brief, understandable overview in English for a middle-school level.

Tropical fish

• They live in warm tropical waters, both freshwater and saltwater.
• They are often colorful and come in many shapes, many around coral reefs.
• Common examples: clownfish, angelfish, neon tetra, guppy.
• Diet: mostly omnivores – eat small plants, algae, and tiny animals.
• Reproduction: many lay eggs; some care for their eggs.

Dolphins

• Dolphins are mammals, not fish; they live in oceans.
• They are social and intelligent, often living in groups called pods.
• They use echolocation to find food and navigate.
• Diet: fish and squid.
• Reproduction: give birth to live young; mothers nurse their calves.
• Breathing: they breathe air through a blowhole.

Key differences

• Fish use gills and usually lay eggs; dolphins breathe air with lungs and nurse young.
• Dolphins are mammals; tropical fish are aquatic animals adapted to warm waters.
