The Santa Águeda stream is a privileged body of water with a large amount of vegetation and species of fish and crustaceans, such as Herichthys tepehua, who has great coloration and behaviors worthy of keeping in an aquarium.
- Underwater landscape
The aquatic vegetation is very diverse and abundant, creating favorable places for shelter, feeding and reproduction. There is little litter on mainly rocky soil and very little water flow.
The most abundant aquatic vegetation is composed of Cabomba, Higrophila and Ludwigias.
Fishes:
- Herichthys tepehua abundant
- Thorichthys maculipinnis few
- Astyanax mexicanus abundant
- Poecilia mexicana abundant
- Xiphophorus variatus few
- Gobiomorus dormitor abundant
- Agonostomus monticula rare
Molluscs:
- Pomacia flajellata abundant
Crustacean:
- Macrobrachium acanthurus abundant
- Atya sp. few
- Procambarus acanthophorus rare
Aquatic plants:
- Heteranthera sp. abundant
- Najas guadalupensis abundant
- Ceratophyllum demersum abundant
- Ludwigia repens abundant
- Egeria densa abundant
- Hygrophila polysperma abundant
- Lemna minor few
- Riccia fluitans few
- Heteranthera reniformis media
- Azolla sp. few
- Hydrocotyle sp. few
- Threats to ecology
The Santa Agueda stream located in the state of Veracruz has easy access to the inhabitants of the region where they catch some fish and crustaceans, without any restriction damaging the ecology of the place.

Comment by the expert
Juan Miguel Artigas Azas: It is a beautiful description of the habitat. My main comments are that it is not mentioned that two of the cichlid species present (Vieja fenestrata and Thorichthys maculipinnis) are in fact newly arrivals introduced by man. A wider description of the river (e.g. width, depth, structure) would have been nice. Some species which are commonly present in Rio Tenixtepec are missing from the list of fish species (e.g. Pseudoxiphophorus jonesii, Gobimorous dormitor, Awaous tasajica).
Jairo Arroyave: The participant offered a very good description of the BIN, including fair-quality photographs (or video stills?) and video of both the terrestrial habitat adjacent to the body of water and the underwater habitat. Characterization of water chemistry is thorough, as is that of fauna and flora of the biotope. The list of fishes and invertebrates seems exhaustive, as well as that of plants, both terrestrial and aquatic. Bibliography and sitography appears sufficient and adequate.
