Guppies are a popular freshwater fish kept by aquarists of all levels. Their small size peaceful temperament and bright colors make them an excellent choice for community aquariums. But could ghost shrimp also live with guppies? Let’s explore the compatibility between these two species.
An Overview of Ghost Shrimp and Guppies
Ghost shrimp, also called glass shrimp, are a widespread crustacean species They thrive in fresh and brackish waters across North and South America Adults reach 1-2 inches long.
Guppies originate from South America and many islands. Selective breeding has produced numerous color morphs and tail types of these lively little fish. But most guppies max out around 1.5-2 inches long as adults.
Both ghost shrimp and guppies are omnivores and very adaptable to different water parameters. This gives them potential to coexist well. But there are a few key considerations.
Size Difference Between Adults
- Adult ghost shrimp are as big or bigger than adult guppies.
- Guppies cannot swallow adult ghost shrimp.
- Small guppies may be seen as prey by large ghost shrimp.
The size difference between adult ghost shrimp and guppies works in the shrimp’s favor. Guppies have small mouths in proportion to their bodies. They could not swallow an adult ghost shrimp.
However, jumbo ghost shrimp nearing 2 inches long could potentially attack and kill undersized guppies under 1 inch. Small fish are seen as prey items to large shrimp.
As long as the guppies are fully grown adults, the ghost shrimp will not be able to eat them. Their size makes them incompatible as ghost shrimp food sources.
Tank Size Needs
- 10+ gallon tank recommended for both species.
- Provides adequate territory and hiding spots.
- Prevents aggression issues from overcrowding.
Ghost shrimp and guppies both require at least a 10 gallon or larger aquarium. This allows proper swimming room for the guppies. It also provides plenty of floor space for shrimp grazing and hiding.
In too small of a tank, both species may become territorial or aggressive. Overcrowding stresses fish and invertebrates alike. A 10+ gallon tank prevents conflict by offering each animal its niche.
Water Parameters and Habitat
- Overlapping temperature, pH, hardness tolerances.
- Both prefer planted tanks with hiding spots.
- Moderate current appreciated.
Ghost shrimp and guppies share similar preferences for water conditions. Both thrive at temperatures of 65-82°F and in soft to moderately hard water. A neutral pH close to 7 is ideal for both.
While ghost shrimp spend more time on tank surfaces, both species welcome planted aquariums with driftwood, rock caves, etc. These elements provide security and break line of sight.
A moderate current from a filter outflow or air stone is beneficial. It oxygenates the water and provides a steady food source. Stagnant tanks can starve ghost shrimp.
Temperament and Interactions
- Guppies mildly curious but then ignore shrimp.
- Ghost shrimp very shy and evasive.
- Little direct interaction once established.
Guppies initially investigate new shrimp tankmates. But ghost shrimp flee rapidly from fish. This deters any nibbling or fin nipping behaviors from curious guppies.
Once shrimp establish hiding spots, interactions are minimal. Guppies focus on mid to upper tank levels. Ghost shrimp stick to lower regions and rarely encounter each other.
Overall, guppies and ghost shrimp coexist very peacefully. Their sizes, temperaments, and uses of tank space allow comfortable cohabitation.
Diet and Feeding Considerations
- Guppies are omnivores that may eat baby shrimp.
- Adult shrimp scavenge algae, biofilm.
- Supplement shrimp diet with sinking pellets.
Since guppies are omnivores, they may prey on newly hatched juvenile shrimp. Adult ghost shrimp are safe due to their size. But you may lose offspring to guppy predation.
Ghost shrimp thrive on naturally occurring algae, biofilms, and detritus in the tank. But offering shrimp-safe sinking pellets enhances their diet. This discourages any interest in guppy fry.
Take care not to overfeed guppies. Uneaten food fouls the water, which shrimp are highly sensitive to. Target feed guppies several times a day and remove any excess.
Breeding Behaviors
- Guppies are livebearers with high fry output.
- Ghost shrimp at risk of being eaten when molting.
- Fry and molted shrimp vulnerable to predation.
Guppies routinely produce fry, with larger females dropping new broods monthly. The high number of babies makes supplemental feeding important so they don’t get eaten.
Ghost shrimp also molt their exoskeletons as they grow. During this time they are very vulnerable. Guppies may pick at molted shells and eat any shrimp caught mid-molt.
So provide ample cover and alternative foods to protect both guppy fry and molting shrimp. This reduces chances of accidental predation between tankmates.
Introducing Ghost Shrimp to an Existing Guppy Tank
To safely add ghost shrimp to a guppy aquarium:
- Acclimate the shrimp slowly to prevent temperature shock.
- Turn off tank lights and release shrimp at night for immediate hiding.
- Feed guppies well before and after adding shrimp to reduce interest.
- Provide plenty of dense planting, rock caves, driftwood, etc for shelter.
- Monitor during the first few days for any aggression issues.
Taking these steps helps ghost shrimp settle in smoothly and safely amongst guppies. The combo can work very well in a 10+ gallon tank with precautions.
Key Takeaways on Guppies and Ghost Shrimp
- Adult ghost shrimp are too large for guppies to eat.
- Shrimp larvae and molts may get eaten by guppy fry.
- A 10+ gallon tank gives both species adequate room.
- Planted tanks with hiding spots keep the peace best.
- Guppies ignore shrimp once acclimated to their presence.
- Supplementing food for both reduces risk of predation.
Ghost shrimp and guppies can certainly coexist well with proper precautions. Their size difference, temperaments, and tank needs allow peaceful cohabitation. Follow the tips above for the best chance of success keeping these two popular aquarium animals together.
Frequently Asked Questions About Guppies and Ghost Shrimp
Can ghost shrimp attack or kill guppies?
Adult ghost shrimp will not kill healthy adult guppies. They could potentially kill undersized juvenile guppies. But guppies are too fast for shrimp to catch once mature.
Do ghost shrimp eat guppy fry?
Ghost shrimp may opportunistically eat newborn guppy fry if they can catch them. But they do not directly hunt guppy babies. Keeping shrimp well fed reduces any interest in eating fry.
How many ghost shrimp can live with guppies?
A good rule of thumb is 1 ghost shrimp per 2-3 guppies in a 10 gallon tank. Increase shrimp numbers slowly over time. Have at least 5-6 shrimp to spread aggression and prevent targeting specific individuals.
What tank size do guppies and ghost shrimp need?
A 10 gallon tank is the recommended minimum size for housing guppies and ghost shrimp together. This allows ample room and reduces aggression from tight quarters.
Should you add ghost shrimp or guppies to the tank first?
It’s generally best to establish the guppy population first, then add ghost shrimp later. This prevents shrimp from claiming territory that guppies may want, which could increase conflict.
