Loaches and shrimp are both popular choices for home aquariums. Their lively behavior and colorful appearances make them fun additions that can bring vibrancy to any tank However, one common question that arises is – will loaches eat shrimp if housed together?
The answer is not simply yes or no. Loach compatibility with shrimp depends greatly on the species of loach, the shrimp types kept, tank size, tank mates, and other factors. With proper care and planning, loaches and shrimp can coexist without much trouble. However, there are also scenarios where loaches see shrimp as food.
In this article, we’ll take a detailed look at the nuances of keeping loaches with shrimp. We’ll go over the key considerations, compatibility between different species, best practices for care, and more. Read on to get the full scoop on whether loaches will eat shrimp or not.
Key Factors That Determine Loach and Shrimp Compatibility
Here are some of the most important elements to consider when housing loaches with shrimp
Loach Species
Not all loaches behave the same way. Some species are notoriously more aggressive and predatory than others. For example, larger loaches like clown loaches are known shrimp eaters and should never be paired with shrimp. On the other hand, kuhli loaches and zebra loaches are peaceful bottom dwellers that mostly ignore shrimp. Always research the temperament of the specific loach types you plan to get.
Shrimp Size
In general, large adult shrimp are safer with loaches than tiny juvenile shrimp. Bigger shrimp are less likely to be seen as prey. Large shrimp like Amanos that reach 2 inches have a much better chance of surviving with loaches. Very small shrimp fry may get eaten.
Tank Size
Cramped tanks increase aggression and competition between tank mates. A 10 gallon tank is too small for loaches and shrimp. Aim for at least a 20 gallon tank, with 30+ gallons being ideal. More space allows for plenty of hides and reduces confrontation over territory.
Tank Setup
Provide ample plants, rocks, driftwood, and caves for shrimp to take cover when feeling threatened. Dense vegetation helps block line of sight between loaches and shrimp. Loaches also appreciate caves and hiding spots. Clearly defined territories and barriers are key.
Tank Mates
Avoid keeping loaches with very active or aggressive fish that may intimidate shrimp. Good tank mates include small tetra species, danios, rasboras, and peaceful community fish that won’t compete over the same space as the shrimp.
Feeding
Well-fed loaches are less likely to hunt shrimp. Offer a quality omnivore pellet, treats like bloodworms, blanched veggies, etc. Don’t overfeed, but do provide a varied diet. Supplement with algae wafers, spinach, and shrimp pellets for the shrimp.
By keeping these factors in mind, you can optimize the loach and shrimp environment. Next, let’s look at some specific loach species and their compatibility.
Loach Species and Their Compatibility with Shrimp
Kuhli Loaches
Kuhli loaches are an excellent choice for shrimp tanks. These slender, eel-like fish spend most of their time sifting through substrate. They largely ignore shrimp and are very peaceful. Even small shrimp are relatively safe with kuhlis. Just be sure to give them plenty of sandy substrate to burrow in.
Clown Loaches
Clown loaches should never be kept with shrimp. Growing over 12 inches long, these voracious loaches will eat shrimp readily. Their large size also makes them very dominant tank inhabitants. Dwarf shrimp don’t stand a chance with clowns.
Dojo Loaches
Dojo loaches are moderately risky with shrimp. They can be kept with larger shrimp given plenty of tank space, but may pick off small individuals. It’s best to avoid housing dojos with expensive shrimp to prevent costly losses. They also disturb substrate often, which shrimp dislike.
Yoyo Loaches
Yoyo loaches are somewhat shrimp-safe, but only with careful management. While not quite as predatory as clowns, they do sometimes nip at shrimp and should be monitored. Provide lots of broken sight lines and shrimp may survive. Adding yoyos to an established shrimp colony is recommended.
Zebra Loaches
Zebra loaches are an excellent match for shrimp tanks. Peaceful and calm, they mostly just swim in open water. Zebras rarely bother shrimp, although shrimp fry may get eaten. Overall though, zebra loaches are a smart choice for community tanks with shrimp.
In general, kuhlis, zebras and the smaller loach species are safer options for shrimp. Larger, more aggressive loaches should typically be avoided in shrimp-focused tanks.
Best Practices for Keeping Loaches with Shrimp
If you wish to mix loaches and shrimp, following these best practices will give you the highest chance of success:
-
Research loach species thoroughly and select peaceful ones suitable for community tanks. Kuhlis, zebras, dwarf chain loaches, etc. are good choices.
-
Use at least a 20 gallon tank, with 30-40+ gallons being ideal. Give them space.
-
Include lots of plants, rocks, wood, and tunnels to break up sight lines and create barriers.
-
Introduce young or juvenile shrimp first and let them establish colonies before adding loaches.
-
Add shrimp in large groups at once so they feel secure. Drip acclimate them slowly.
-
Feed loaches well with quality omnivore foods so they are less likely to hunt shrimp.
-
Consider having backup tanks available in case loach and shrimp conflicts arise.
With the right species selection, tank setup, population management, and feeding, loaches and shrimp can live together successfully. Pay close attention and be prepared to separate any aggressive individuals. Patience and proper care is key!
Identifying Danger Signs Between Loaches and Shrimp
It’s important to monitor loach and shrimp interactions closely, especially during the initial integration period. Watch for these red flags:
-
Loaches gorging on shrimp pellets or algae wafers meant for shrimp. This may indicate predatory interest.
-
Loaches staking out spots near shrimp hides or swarming around feeding areas. They may be waiting to ambush.
-
Nipping or chasing behaviors. Any harassment indicates incompatibility between those individuals.
-
Missing shrimp, especially juveniles. Check under decor for remains. Deaths point to predation.
-
Shrimp constantly hiding and acting skittish due to loach presence. This signals an unsafe environment.
-
Lethargic or diminished shrimp populations over time. Predatory pressure taking its toll.
Any of these signs means actions should be taken to protect shrimp. Remove aggressive loaches, add barriers, or separate entirely if needed.
Frequently Asked Questions
Can loaches and shrimp ever coexist peacefully?
Yes, there are certainly many cases of harmonious loach and shrimp tanks. Key factors like species selection, tank size, barriers, and populations levels determine success. With careful setup, most loaches can integrate into shrimp communities without issue.
What bottom-dwelling fish can live with shrimp?
Good bottom fish for shrimp include peaceful loach species like kuhlis, dwarf chain loaches, zebra loaches, etc. Small cory catfish also do well, as do many types of plecos. Avoid large plecos that may damage shrimp. Always research fish behavior before mixing.
Will loaches reproduce with shrimp in the tank?
It is highly unlikely. Shrimp and loaches do not interbreed. However, baby shrimp may become food for some loaches. Loaches also breed best in species-only tanks with specific conditioning. Keep breeding pairs separate from community tanks.
Can loaches go in tanks with live plants?
Most loaches do fine with live plants. Stick to hardy plant species and give loaches plenty of open swimming space. Some may nibble leaves but won’t devour plants. Avoid loaches known to uproot plants like clowns. Add driftwood, rock caves, etc to distract plant-digging.
What bottom feeders clean up after shrimp?
Good options include small cory catfish, otocinclus catfish, kuhli loaches, and dwarf chain loaches. These fish will eat leftover shrimp food, algae, and detritus without harming adult shrimp. Nerite snails and amano shrimp are also excellent cleanup crew.
Conclusion
The question of whether loaches will eat shrimp or not depends greatly on the species involved, tank setup, populations, and care. With smart management, the two can cohabitate successfully. Do your research, stick to peaceful loaches, provide barriers, feed adequately, and monitor interactions. This will allow you to enjoy both loaches and shrimp in one thriving community tank. Be prepared to separate aggressive individuals as needed. Patience
