Ditch the plants or go fake and you can go with a pair or harem of any of the Vieja types and a big group of Thorichthys and /or Cribroheros.. Can swap the Vieja for a C. pearsi or bocourti or Chuco or similar too..
I currently have a pair of V melanura "Lago Peten" a small group of O heterospila and a group of T. meeki in a 240, w/ zero issues.. I personnaly have no experience with them and plants...
Also had Vieja group, C. robertsoni group and T. meeki group in another tank that worked well other than the robertsoni and meeki beefing occasionally...
Yeah either the robertsino or meeki, just want one bottom dwelling group that shows some natural behavior/interaction. Leaning Meeki. Ok, starting to realize I really need to give up on the plants.
Do you have a picture or video of that tank?
Checking the stock list of my LFS they have these types:
Cincelichthys bocourti Lago Izabal
Cincelichthys pearsei Lacanjah
Amphilophus flaveolus Lake Apoyo F2
Herichthys carpintis Escondido
Herichthys tamasopoensis
Herichthys deppi
Maskaheros argenteus
Maskaheros regani
Oscura heterospila
Vieja bifasciata Rio Chacamax
Vieja bifasciata Rio Teapa
Vieja breidohri
Vieja guttulata
Vieja maculicauda
Vieja melanura Belize F1
Vieja melanura Belize F2
Vieja synspilum/melanura
Vieja synspilum/melanura Lago Peten
Vieja synspilum/melanura Spotted
Vieja zonata Rio Perro
Skipped the amatitlania, parachromis and thorychthis species.
Ok, so let's say I stock with 8 (?) meeki, how would you complete a stocking list for the 320g?
