Species to Avoid in a Pleco Aquarium

Not all aquarium species are compatible tank mates for Plecos. If you are setting up a new environment, here are some creatures to avoid:

1. Goldfish

Goldfish and Plecos have unaligned temperature and food preferences, making them unsuitable tank mates.

The higher waste output from Goldfish could spoil the water quality, negatively affecting the Plecos.

Temperature Mismatch: Goldfish prefer cooler water (65-75°F), unlike Plecos who need warmer water (74-80°F), setting the stage for an incompatible living situation.
Dietary Discrepancies: Goldfish mainly consume flakes or pellets, while Plecos munch on algae, causing potential dietary conflicts.
Ammonia Emission: The increased waste and ammonia from Goldfish can critically endanger Plecos by deteriorating water conditions.
Size Contrast: The substantial size difference may cause unintentional harm, especially as Plecos enlarge, accidentally hurting smaller Goldfish.

2. Flowerhorn Cichlid

Known for their assertive behavior, Flowerhorn Cichlids are unfit partners for the gentler Plecos. This aggressive trait can create tension and damage to Plecos in a joint habitat.

Aggressive Tendencies: Flowerhorns’ aggression can inflict serious harm or anxiety to Plecos.
Territorial Challenges: The territorial behavior of Flowerhorns can prompt disputes and unlivable conditions for Plecos.
Diverse Dietary Needs: Varied dietary needs between Flowerhorns and Plecos may lead to malnutrition.
Size and Power: Flowerhorns’ size and force can unintentionally damage the tranquil Plecos, making shared living space hazardous.

3. Puffer Fish

Puffer Fish, potentially aggressive towards Plecos, have distinct dietary and habitat requirements, making them unsuitable tank mates.

Possible Aggression: Puffer Fish’s aggression could endanger Plecos’ safety.
Unique Dietary Needs: Puffers’ preference for meaty food contrasts Plecos’ primarily vegetarian diet, causing feeding issues.
Habitat Discrepancies: Preferring brackish water, Puffer Fish create an unsuitable environment for freshwater Plecos.
Sensitivity: Puffers’ sensitivity to environmental shifts can heighten with other species like Plecos, leading to health complications.

4. Crayfish

Crayfish pose a predatory threat to Plecos, especially smaller or juvenile ones. Their aggressive and territorial behavior is inconsistent with the peaceful nature of Plecos.

Predatory Danger: Crayfish might target smaller Plecos, presenting significant safety risks.
Territorial Conduct: Much like Flowerhorns, the territoriality of Crayfish can produce hazardous conditions for Plecos.
Food Rivalry: Potential food competition between Crayfish and Plecos could lead to malnourishment or starvation.
Habitat Disparity: Crayfish’s preference for cooler, structured environments might not suit Plecos, causing unease and tension.

5. Turtles

Turtles could mistake Plecos for food, and their untidy eating habits can spoil water quality, harmful for Plecos.

Potential for Predation: Turtles might regard smaller Plecos as food, leading to a risk of predation.
Untidy Eating Behavior: Turtles’ messy eating could worsen water quality, crucial for the health of Plecos.
Temperature Differences: Typically needing different temperature conditions, turtles do not align with the optimal conditions for Plecos.
Space Encroachment: Turtles might dominate substantial space, restricting area for Plecos, and inducing possible stress and discomfort.

Which Fish Species Won’t Eat Pleco Fry

Many fish species are indifferent to pleco fry, preferring other types of food or simply coexisting peacefully.

However, it’s important to choose tank mates wisely to ensure the survival of young plecos.

Tetras: Smaller species like neon or cardinal tetras typically focus on eating small insects and won’t bother pleco fry.
Corydoras Catfish: Bottom dwellers like plecos, they rummage for food but generally leave pleco fry alone.
Livebearers: Guppies, mollies, and platies are mostly interested in flake food and small invertebrates, not young plecos.
Certain Cichlids: While many cichlids are aggressive, dwarf varieties such as the Apistogramma show less interest in pleco fry.
Rasboras: Peaceful swimmers like harlequin rasboras concentrate on mid-water feeding and rarely disturb plecos at the bottom.
