Safety Summary

✔ Safe: Yes — blanched, for herbivorous species
⚠ Use caution: Hard raw carrots are difficult to eat
✖ Toxic: No

Why

Blanched carrots are a safe vegetable supplement for herbivorous freshwater fish like goldfish, koi, and plecos. Raw carrot is too hard for most fish to eat. Briefly blanching softens them to an appropriate texture. Carrots provide beta-carotene which can enhance the coloration of orange and red fish. They won't benefit carnivorous fish species.

Portion Guidance

Small blanched pieces a few times per week. Remove uneaten portions within 24 hours.

Risks & Symptoms

Raw carrot: fish can't eat it effectively
Uneaten food: water quality decline
Not beneficial for carnivorous fish
