Protecting Water Hyacinth Roots from Goldfish in an Indoor Atrium Pond

Goldfish Eat Roots

It's not "falling off"—they're grazing. Goldfish love hyacinth roots.

Floating Mesh Islands: Commercial or DIY (pool noodle frame + mesh). Roots grow through; fish can't reach.
Larger Filter Intake: Coarse pre-filter sponge reduces clogging frequency.
Liquid Fertilizer: Compensates for root loss (e.g., Seachem Flourish).
Replace if Needed: Hyacinths are cheap. Sometimes easier than fighting.

Atrium should provide enough light. Keep water 65-75°F for best growth.
