This is my first tank I have ever owned let me know honestly what you guys think and how my set up is what I can do to make it better. I am currently housing 1 6" silver arowana, 2 Sveni ciclids(Male 4"-Female 3"), 2 whiptail plecos, 1 albino bristlenose pleco, 1 farowella, 1 whiptail farowella, 2 other unknown species catfish, 3 bamboo shrimp and 5 fiddler crabs. The 75 gallon tank they are in consistantly is stocked with 1.5-3 dozen feeder guppies, 2-3 dozen feeder ghost shrimp and 1-2 times a day I feed them live blood worms. Also I have 9 varieties of live plants total of around 13-14 groups of plants. 63 lbs of slate rock for cover and 100lbs of dime-nickle size rocks as my base. Current filtration is helped by a penn-plax cascade 700(soon to be upgraded to a FX5 with a custom spray bar). Water circulation is helped out with a Tetra 100 gallon air pump attached to 2 attached 23" bubble bars buried under the rock on the backside of my tank as well as a RIO 2500 power head(only turned on for a couple hours a day to help circulate any debri or leaves from plants) What do you guys think of this set up?
