A Minecraft player has pointed out a devastating issue relating to the dolphins of the voxel world, asking why the aquatic mammals cannot survive within an aquarium. Minecraft's dolphins are known as neutral mobs within the sandbox game that usually reside in non-frozen ocean biomes. The intelligent sea creatures can give players a speed boost when they are swimming close by and feeding them raw cod or salmon can improve their trust in the player, which is a fantastic element for animal lovers.
