To all seniors,

Recently, I have an outbreak of pests on the wall of my tank.

I have this reef tank for almost 3 years now.

I need help to ID this pest. Photographs attached below.

Can anyone help to answer the following questions?

1. What is the name of the pests?

2. What is the cause of the outbreak?

3. Are they harmful to my fish or Coral?

4. How do I get rid of them?

5. What should I do?

I appreciate any help from any kind person in this forum

1. What is the name of the pests?

Flatworms

2. What is the cause of the outbreak?

They normally come with yr newly purchase corals or Live Rock as hitchhiker.. Why they bloom? Check yr feeding routine or tank nutrient level.

3. Are they harmful to my fish or Coral?

This type may only cause irritation to some corals but not really harm... but long term may result some negative impact as another indication of high nutrient

4. How do I get rid of them?

Try velvet nudibranch, Yellow Wrasses, Mystery wrasse, Radiant wrasses or Siphon them when WC..

5. What should I do?

"Frequent WC, Siphon them manually get flatworm predators.."

Good Luck....
