Alien lifeforms may have unexpected applications. Utilizing alien resources is a proven survival strategy.File:BladderfishVO.ogg

― PDA, Dialogue

The Bladderfish is a small, passive fauna species. It can be caught and is edible, mostly populating in the Safe Shallows and the Grand Reef.

The Bladderfish stands out in comparison to other small fish, as it can be used to craft Filtered Water. As a result, Bladderfish are a good source of H₂O, though not as good as Disinfected Water and Large Filtered Water.

Being slow and passive, Bladderfish are easy to catch, especially during night time, when they are next to immobile due to their diurnal properties.

Eating a raw Bladderfish will restore fifteen points of Oxygen, which can save the player in certain situations. This only works in survival and hardcore modes.

Appearance

The Bladderfish is a small creature comprised of a long, extremely thin main body with pale-purple coloured translucent bladders on top and bottom. These bladders have slim tubes protruding from their outer edges, the tips of which glow pink.

The Bladderfish's head is bright orange and ovular in shape, possessing a pair of large eyes and no mouth. The bladders have a faint violet bioluminescent glow. Its main body is reddish-pink with light green spots.

Behavior

The Bladderfish swims by contracting and expanding its bladders, constantly altering its speed between fast and slow. Bladderfish shoals can currently only be found following Reefback Leviathans. At any other place they are mostly found alone or in very small groups.

The Bladderfish will flee from the player upon being approached.

Comparison to Tanks

Bladderfish, interestingly, is a viable option to extend periods of diving rather than carrying additional tanks in the inventory. However, this strategy has the downside of dehydration caused by eating raw bladderfish, which may require the player to carry extra sources of water, as well as additional time needed for growth.

• Each Bladderfish only takes up 1 inventory space and replenishes 15 units of O₂
• Standard O₂ Tank takes up 6 inventory spaces and will replenish 30 units of O₂ making it 5 units per slot
• High Capacity O₂ Tank and Lightweight High Capacity Tank take up 6 inventory spaces and will replenish 90 units of O₂ making it 15 units per slot, which is equivalent to the Bladderfish
• Ultra High Capacity Tank takes up 9 inventory spaces and will replenish 180 units of O₂ making it 20 units per slot. Which makes it the only tank that will replenish more O₂ per slot than the Bladderfish. However, unlike the Bladderfish or other tanks carrying additional Ultra High Capacity Tanks will reduce the players Swimming Speed
  • This may in fact be the reason why other tanks do not reduce Swimming Speed

Hence, breeding Bladderfish in an Alien Containment can be a better option than crafting additional Tanks. Bladderfish use inventory space more efficiently, do not require materials to craft, do not reduce Swimming Speed, and, when consumed, will free up inventory space unlike swapping tanks. They do have numerous downsides however, being the dehydration they cause, which may require the player to carry extra sources of water; it is inefficient to replenish oxygen this way as other tanks do not require any materials for refilling and furthermore do so much quicker than bladderfish do.

In conclusion both ways have their own pros and cons and thus usage largely depends on the situation. The most practical option is simply to operate near a powered submersible.

Data Bank Entry

This unusual herbivore appears to be mostly defenseless, and bears little resemblance to the other lifeforms around it. 1. Semi-permeable Bladder: The bladderfish is able to filter air and seawater into its body cavity through a unique membrane which surrounds its spine like a bladder. This allows it to remove and consume organic particulate caught on the way, and adjust its buoyancy. 2. Open-ended Vascular Tubing: Can be angled and contracted to pump out water and achieve low-velocity, guided propulsion. Largely oblivious to threats, and practically immobile at night, its only identified defense mechanism is that it's composed almost entirely of water, air and cartilage. Assessment: Edible (oxygen may be retrieved from the bladder and added to tanks on consumption); membrane has applications as a natural water filter
