Betta fish diseases look frightening, but most of them follow a pattern: something in the tank goes wrong first (dirty water, cold water or stress), and the illness follows. This page is the starting point for any sick betta. Use the symptom checker to find the likely problem and how urgent it is, follow the

Betta ich is the most likely culprit if your betta is suddenly covered in tiny white salt-like spots, and it’s one of the most common and most curable fish parasites, as long as you treat it correctly and for long enough.

Betta septicemia is a bacterial infection of the bloodstream, and the hallmark warning sign, red streaks or blood-red patches under the scales and in the fins, should be treated as a same-day emergency because septicemia can kill within days. This guide shows you exactly how to distinguish true red streaking from a betta’s natural red

Knowing how to revive a dying betta matters most when your fish is lying at the bottom of the tank, barely moving, not eating, or breathing weakly, because a “dying” betta is often far more recoverable than it looks, since the most common causes (ammonia poisoning, cold shock, low oxygen) are fast to fix if

A betta losing color, fading, turning pale, washing out, or shifting to white or black, is very often completely harmless, especially when it’s the natural marble gene at work. The key skill is telling normal genetic color change apart from a stress, water-quality, or disease warning. This guide explains all seven causes of a betta

Betta dropsy is the condition every betta keeper dreads, the unmistakable “pinecone” of raised scales that signals internal organ failure and fluid build-up. This guide tells you the honest truth: what dropsy actually is, how to confirm it with the from-above test, the best-effort Epsom-salt and antibiotic protocol, realistic survival odds, what causes it so
