An aquarium houses several fish species

An aquarium houses several fish species. In the foreground, two yellow plecos are nestled together, their mouths fused to the glass. To their left is a clump of green aquatic moss. In the midground, a pink tetra with a white belly swims to the left, its fins fanned out. Behind it, green aquatic plants fill the tank, and a black filter rises from the background. The gravel substrate of the tank is a mix of black and red. The image is shot from a close-up perspective, and the lighting appears to be natural, coming from above.
