Pygmy Corydoras Habitat Requirements

Pygmy Corydoras common health issues <h3>Ich (White Spot Disease)</h3><a href="https://totalpond.com/blogs/articles/most-common-fish-diseases-and-how-to-prevent-them#" rel="noopener noreferrer" target="_blank">Ich</a> is a parasite that shows as tiny white dots on fins and the body. Infected fish may scratch against objects and breathe fast. To cure that, raise the temperature slightly (carefully), do partial water changes, and use a reliable ich treatment medication following instructions. Salt baths (for species that tolerate it) or medicated anti-parasitic drops can help. Quarantine new fish to prevent ich from entering your tank. <h3>Fin rot (bacterial infection)</h3><a href="https://totalpond.com/blogs/articles/most-common-fish-diseases-and-how-to-prevent-them#" rel="noopener noreferrer" target="_blank">Fin rot</a> causes frayed, slimy, or disappearing fins. It often appears after poor water quality or injury. The condition can be treated by improving the water quality (especially the nitrates), removing any tankmates that are stressing the fish, adding a broad-spectrum antibacterial medication, and maintaining good water quality and feeding.<h3>Barbel damage and fungal/bacterial infections</h3>Pygmy Corydoras have small, sensitive barbels; a sharp substrate or sand with grit can cause bleeding and even <a href="https://totalpond.com/blogs/articles/most-common-fish-diseases-and-how-to-prevent-them#" rel="noopener noreferrer" target="_blank">infection</a> (redness, swelling) if they are damaged. Prevent this by using fine sand and gentle cleaning. If infection appears, clean water, salt dips where appropriate, and antibacterial treatment for fish can help. A good diet and low stress speed recovery. <h3>Pygmy Corydoras General Health Tips</h3><ol><li data-list="bullet">Keep water clean with regular partial changes</li><li data-list="bullet">Use fine sand substrate</li><li data-list="bullet">Keep them in groups (<a href="https://www.aquariumcoop.com/blogs/aquarium/pygmy-corydoras?srsltid=AfmBOop9DkqlhgC-6gz6E0Zh6XMncj-Qf0MX0bYYIDY509hLX3GY-OQM&amp;utm_" rel="noopener noreferrer" target="_blank">10+</a> if possible) and avoid boisterous tankmates</li><li data-list="bullet">Quarantine new arrivals before adding to the main tank</li><li data-list="bullet">Feed varied foods and don’t overfeed</li></ol>
