Today I started making the Biotope by removing most of the substrate (brown sand and black aqua soil mixed) to replace with Pool Filter Sand or Play Sand. I moved the Craggy Head Banjo Catfish to the 55 Gallon. Once I finish growing out my baby Longnose Gar and Blind Cave Tetra I’ll move them to the 55. I want to have Cypress Stumps or Cypress Knees in the tank but with prices from good looking ones being $100 + I’ll probably make them myself with spray foam. Plant suggestions and stocking suggestions (check a previous post) would be appreciated.
