The area is semiarid, with cacti other succulents; a densely woody area of cedar around the springs, except on the eastern side. Formerly the water was crystal clear at 19-20°C, but recently after depletion, the water is brown. Aquatic vegetation includes Ceratophyllum, Potamogeton, Typha, Eleocharis, Lemna, Utricularia, Scirpus, and Chara; crayfish Cambarellus sp. was observed. The bottom is loamy or muddy (Ref. 26729). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139). Lozano-Vilano, M. de L. and S.
