There are eleven loaches ranging from 5-6" The Tigrinus is about 14" The bigger widebar is about 9" and the armatus is 7-8" There is also a gold wolfish an endli and a pike cichlid. I have some Indo and Thin bar dats coming next week and I have a leichardti and some "type" of ATF growing out. That will probably be it for now. I am in the process of planning a possible 600 or 750 gallon and if so I will add more fish but at the moment these fish are going to fill the 300.
Right now the filtration is kinda of just thrown together as I pulled filters off other tanks to speed the process. I am running a wet dry filter I have two acrylic style boxes that each sit inside a 54 gallon rubbermaid tub which I have connected with pvc and bulkheads. I am running approx. 2100 gph thru the wet dry. I have about 15 liters of eheim pro substrat. supposedly 5 liters equates to around 500 gallons. I also have a few hundred dollars of cell pore. I have an FX5 canister and an Xp2 right now but they are not permanent. I also have two Pentair aquatics Fluidized sand filters.
Eventually I will only be running the Wet dry and the two sand filters. I will also remove the sand filters and the heaters from the tank and move them to the sump so the tank will look a lot cleaner.
