Recently I posted a video of a new 75 gallon tank that my son and I built. Well, Petco had a sale on tanks so we combined platies from a 55 and guppies from a 35 together. Trying to consolidate here. This tank is Low Tech, no CO2, low light, dirted substrate with pool filter sand. I basically have an assortment of Sword plants, dwarf Sagittaria, and excess plants from other tanks.
