5 – Rotting or Fraying Finsįin rot is a condition caused by bacterial and/or fungal infection. Once you rule out the possibility of poor water quality, consult a veterinarian so he/she can help you treat your fish. The major causes of cloudy eye disease include injury, infection, and poor water quality. If your pleco appears to have cloudy eyes (i.e., eyes covered with whitish/gray slime), this might be a sign of an underlying disease or injury that may or may not be deadly. Here are some other symptoms to look out for: Plecos who have this condition often have hugely swollen bellies, as if bloated, and bulging eyes. It’s characterized by the swelling of soft tissues due to fluid build-up inside the fish’s body cavity or tissues. Unlike ich, dropsy is a symptom of an underlying disease (i.e., parasitic infections, bacterial infections, or liver dysfunction). Zebra, clown, and snowball plecos: 30 gallonsĢ – Spots or Fungus on Gills, Fins, or Body.For other species, here are the minimum required tank sizes: Likewise, adult common plecos need to be placed in a tank of at least 150 gallons. Temperatures in the high 50s might be okay for a while, but it needs to be corrected as soon as possible lest the fish die of stress or disease. Most plecos prefer temperatures between 72 to 78☏, but they’re tolerant of water conditions ranging from 65 to 85☏. Water temperature is just as important as pH and alkalinity. You can test your water’s pH and alkalinity with a water test kit. If your pleco is wild-caught, it requires a pH level of 5.5 to 7.0 and alkalinity below 3° dKH (54 ppm). The water needs to be at a pH level of 7.0 to 8.0 and alkalinity between 3° and 10° dKH. Plecos are freshwater fish, so you shouldn’t ever place them amongst saltwater fish. Like most fish, plecos also have specific tank environment needs. Then, give your plecos enough hiding spots or redesign the tank to reduce aggression. Identify the source of the problem and see what you can do about it.įor instance, if you believe the source of your pleco’s stress is caused by aggressive tank mates, separate the pleco into a different tank. Stress occurs for a number of reasons, including temperature fluctuations, aggressive tank mates, underfeeding, and wrong pH levels. Symptoms of stress in plecos include the following: If your pleco is overly stressed and you don’t do anything about it, it’ll likely die within a few days, weeks, or months. Stress is one of the deadliest killers of pet fish.
