Water Parameter And Tank Size

You can use 200 liters or 50 gallons of tank size for your Elephantnose fish to make it comfortable. As they prefer slow flow levels of water, so always make sure that the movement of water is not stressing your fish.

SeaClear 50 gal Acrylic Aquarium Combo Set, 36 by 15 by 20 inches in Black would be a standard aquarium for your Peter’s Elephantnose.

You can arrange slightly acidic water or neutral water to let it thrive in captivity.

You should be very conscious about the water condition as these fish are very sensitive to any change in water conditions. However, it does not mean that beginners should not welcome them.

If you manage to maintain the following water parameters then no matter you are a beginner you can make a favorable environment for your new member.

Some articles about the aquarium water parameters you may like:

pH Level 6.5 7.2
Temperature  73F 82F
Hardness  4dGH 18dGH
Ammonia 0 ppm
Nitrite  0 ppm
Nitrate  <30 ppm
Water flow Slow

Lighting

As you come to know by far that they are shy and timid they prefer low lighting environments. So, you should use dim or subdued light in the aquarium to make your fish feel comfortable.

The nocturnal way of living of this fish demands you not to use high beam light just to make your aquarium look beautiful. Instead, why not go with the preference of your fish to live in limited lightings.

You can have adjustable light and maintain the light by red only lighting for the day time as they cannot see red light. And you can use bright lighting at night for plants. Therefore, your fish would feel good about its environment.

Also, keep in mind that these fish do not get disadvantaged by the limited light when kept with other fish. You can adjust the lighting as per requirement when there is a fish mate in the aquarium. As per some hobbyists, Peter’s Elephantnose fish also adjust in a well-lit aquarium when kept with comfortable mates.

I would suggest you a NICREW ClassicLED Aquarium Light, Fish Tank Light with Extendable Brackets, 48-Inch of 32 Watts for your fish tank.

Substrate Type

Peter’s Elephantnose fish love to be at the bottom of the aquarium. So you should start with the very bottom of the aquarium for making them feel comfortable by considering their sensitivity to hard objects.

Soft sand would be a great option for your sensitive Peter’s Elephantnose fish. As they would not only be comfortable but also you can prevent them from the injury that hard substrate could cause.

Therefore never go for hard gravel. Instead, you can get polished gravel with peat crumbs for soil mechanism or river sand to give your fish a natural vibe in your aquarium. You would see Elephantnose fish peaking on sand which they are hunting for food as they love doing it.

Carib Sea SuperNaturals Peace River (20LB) would be a good substrate if you are looking for one.

Decorations

As you are welcoming your fish at your home so you would want your fish in a beautiful aquarium. make sure you have well planned for setting up the aquarium in the right place where it adorns your room.

Use soft gravel and soil to place it at the bottom to make it easy for bottom swimmer fish to survive.

Elephant nose fish produce a sound when they emit electrical pulses. You can install a sound amplifier rod inside the aquarium that will allow you to enjoy the sound louder.

Natural Plants

The Elephantnose fish love to be in more dense natural vegetation where there are well-grown plants. Therefore, you can arrange various types of plants inside the aquarium.

Salvinia and Water Wisteria is a fast-growing plant that you can install in your tank. These plants contribute to taking control of the level of ammonia, nitrites, and nitrates. Therefore these plants would help in maintaining good water condition.

Java Moss is another plant that grows slowly and does not require much care. Your fish can have a place to hide as they are so dense that it gives your fish a dark place to chill.

But if you are not willing to keep real plants then you can use an artificial plant. Make sure you have enough decor plants, install pipes and hollow logs to provide a hiding spot to reduce stress.

Tank Mates

Calm and peace-loving Peter’s Elephantnose fish can easily cope up with 4 to 7 species in school. But you have to keep in mind that these fish need enough space to deal with their timid behavior.

In the natural habitat, these fish can easily live with their kind but when it comes to tanks or aquariums, they prefer to have space. Keeping them together with their kind would lead to inevitable aggression among them. Due to their territorial nature, you would have to make sure that you manage enough room for them along with other fish.

Filtration (Aquarium Maintenance)

Setting up your aquarium is not only enough to make captivity adjustable for your fish. Besides that, you must also take care of the aquarium time and again by filtration. The water condition must be checked and maintained as per the preferred water parameter for Peter’s Elephantnose fish.

As Elephantnose fish’s big brain requires more oxygen. Its brain uses about 60% of the oxygen the fish intake which they absorb from the water in the tank.

This leaves you with the only choice that you filter the water at least once a week as all impurities water stays down where most of the time your fish like to stay or swim.

So to maintain the water in the good and favorable condition you can install a canister filter or sump filter. Do not use a filter that makes louder noise and leads to maximum movement of water in the aquarium.

I recommend Penn Plax Cascade CCF3UL Canister Filter For Large Aquariums and Fish Tanks – Up To 100 Gallons, Filters 265 GPH. Similarly, OEM Delonghi Sump, Filter, Handle Assembly Shipped With EC685W, EC685M, EC685BK, EC680 can be a great sump filter.

Furthermore, you can also use water care and meds such as de-chlorinator, API general cure, Maracyn-two, and Ich-x. But, changing your aquarium water more frequently would be great.
