Crayfish with cichlids refers to housing crayfish and cichlid fish together in the same aquarium. Some aquarists choose to combine these two types of aquatic creatures due to their compatible water parameters and ability to coexist peacefully. This article will provide an overview of general considerations for keeping crayfish with cichlids.
Introducing Crayfish with Cichlids
Crayfish and cichlids can make interesting tankmates under the right conditions. Some popular crayfish kept with cichlids include the Electric Blue Crayfish and the Mexican Dwarf Crayfish. These species add a pop of bright color with their blue claws and red markings. Cichlids like convicts, kribs, and rams complement them nicely in a decorated tank with plenty of hiding spots.
General Information
- Origin: Crayfish are native to freshwater streams and rivers around the world. Popular species for home aquariums originate from Mexico, Florida, Louisiana, and Tasmania. Cichlids have a very diverse origin spanning across Africa, the Americas, and Madagascar.
- Size: Most crayfish reach 3-5 inches. Mexican dwarf crayfish stay under 2.5 inches. Cichlids vary greatly in max size depending on species, from 4 inches for dwarf cichlids to 12+ inches for larger varieties.
- Lifespan: Approximately 2-3 years is common for both crayfish and cichlids in home aquaria. Some cichlid species may exceed 10 years with proper care.
- Temperament: Crayfish tend to be solitary and territorial. Cichlids run the gamut from very aggressive to community-friendly. Choosing mild-mannered species is key.
- Appearance: Crayfish have a crustacean-like appearance with claws, segmented bodies, and long tails. Cichlids are fish with elongated, oval-shaped bodies and finned tails. Coloration spans the rainbow.
- Popular Varieties: Electric blue, orange dwarf, Mexican dwarf, marbled, and white specter crayfish. For cichlids – kribs, rams, convicts, firemouths, and discus.
- Price: $3-$25 for juvenile crayfish, $5-$50 for juvenile cichlids. Rarer species cost more.
Habitat and Tank Requirements
- Natural Habitat: Crayfish live in freshwater lakes, rivers, and streams. Cichlids inhabit all types of tropical freshwaters from lakes to rapids.
- Tank Size: 30 gallons minimum. A 40 breeder or larger is ideal.
- Water Parameters: Both prefer warm water from 72-82°F, pH 6-8, moderate hardness. Strong filtration is a must.
- Tank Setup: Densely planted with driftwood, rocks, and hiding caves. Substrate can be gravel, sand, or aquarium soil.
Feeding
- Diet: Omnivorous, will eat fish flakes, pellets, frozen or live foods, vegetables, algae wafers.
- Feeding Habits: Both forage along the bottom and throughout tank. Crayfish are notorious nibblers. Cichlids are aggressive eaters.
- Quality Foods: Hikari Algae Wafers, Omega One Shrimp Pellets, Fluval Bug Bites, blanched zucchini, spirulina, shrimp, bloodworms.
Breeding
- Reproduction: Most crayfish and cichlids are egg layers. Many cichlids form pair bonds and provide parental care.
- Breeding Requirements: Condition with high quality foods. Provide suitable spawning sites like caves or flat rocks. Maintain clean, warm water.
- Spawning Process: Courting differs but usually involves color changes in fish. Females lay hundreds of eggs that are fertilized. Parents will tend the eggs until they hatch in some species.
Common Health Issues
- Both prone to parasitic infestations like ich if water quality declines. Bacterial infections also possible. Watch for clamped fins, spotting.
- Prevent with quarantining, proper acclimation. Maintain pristine water through testing and frequent partial water changes. Varied diet and appropriate tankmates also promote health.
Special Considerations
- Compatibility: Avoid very aggressive cichlids like oscars and dovii. Best choices are passive community cichlids.
- Care: Test water parameters frequently. Remediate any ammonia/nitrite spikes quickly. Observe inhabitants for signs of stress or aggression.
- Legalities: None in general. Research specific exotic species regulations.
Compatible Tankmates
Kribensis, rams, convicts, firemouth cichlids, mollies, platies, tetras, plecos, loaches.
Sexing Crayfish and Cichlids
- Crayfish: Males have larger claws and narrower tail flap. Females exhibit smaller claws and wider tail.
- Cichlids: Males are often larger, brighter colored with extended fins. Females are plainer, with a blunt genital papilla.
