Comment by the expert

Ad Konings:

Criteria 5: The aquarium is too small for 10 B. longipinnis as it grows to at least 15 cm. Also P. sacrimontes will not be able to raise any young.
Criteria 6: Never been to the Imo River drainage but if the GPS coordinates are correct the creek looks like an isolated meander of the river (oxbow), which means that there is negligible flow and very unlikely to have round stones in it or at least exposed like they are in this aquarium (but Heiko Bleher can correct me here).
Criteria 7: Aquarium looks very attractive but doubt this is a replica of the natural.
Criteria 8: The chemical composition of the water is incorrect. PH probably should be 5.8 (not 58); the GH and KH are the values really mg/L or do you mean degrees? Dissolved oxygen should be close to 100% for the large tetras to survive, and is probably much higher than the 60% given with a huge 2000L/hr filter.
Criteria 9: Brycinus shown for 7 seconds, 120 sec for pair of Pelvicachromis. All in close up. No video of entire aquarium.

Michael Salter: Only the link to Heiko Bleher’s BIN was provided, with no elaboration whatsoever. Water parameters provided are very inaccurate. The authenticity of this biotope is dubious at best, as is often the case for West African biotopes. Where is the detailed BIN to support it? It is purely imaginative. The size is far too small for the fully matured inhabitants long-term.
