You asked if anyone would like to know more about them? I would.
Stock, lighting, ferts, etc. Basically I want to know all
What is being used as a stand/support for the top tank?
Thanks indeed for the compliments. To answer your questions:
The top tank (the 70g) is on a 3/4 inch sheet of plywood which sits on two columns each made of 3 standard concrete blocks. It "appears" to be sagging in the photo, but in actuality it is dead level; my inexpensive camera distorted the tanks a bit, as both appear to have curves top and bottom. The 90g sits on a regular cast iron frame aquarium stand.
Aside from the inhabitants, both tanks are setup the same. Regular aquarium gravel for substrate (darker type in the 90g), no substrate additives except plant tabs under a couple of the larger Echinodorus in the 90g but I only added those yesterday. Eheim Professionel filters/heater. Lighting is two 48" flurescent tubes, full specrum (one Life-Glo tube and one daylight deluxe or similar on each tank), on for 13 hours daily. There is daylight from the west window in the room. Partial water change weekly, usually 40% of tank volume. Liquid trace element fertilizer (presently using Seachem's Flourish Comprehensive Supplement, but previously had equal success with Kent supplement) added after each water change. Water is slightly acidic (diurnal variation 6.4 to 6.6), tap water is presently 6.8 and very soft. I have a small nylon bag with 3-4 tablespoons of dolomite in the top filter chamberto keep the pH from dropping below 6.2 which it has done probably partly due to the occasional drop in pH of our water to below 6, and this seems to keep it steady. Temp is steady at 25-26C (77-79F) with a deliberate drop of 1-2 degrees max at each water change.
Plants are various species of Echinodorus and Cryptocoryne, Hydrocotyle leucocephala and Sagittaria sp. in the 90g, and in the 70g various Echinodorus species, Sagittaria sp, Anubias nana and floating Ceratopteris.
Fish in the 70g are Carnegiella marthae marthae (4), C. myersi (2), C. strigata strigata (3) and C. strigata fasciata (2), Nannobrycon eques (9), Paracheirodon simulans (11), Poecilocharax weitzmani (7), Hyphessobrycon loretoensis (1) and H. peruvianus? (7), unnamed Hyphessobrycon species (5), Farlowella sp. (1), Aspidoras pauciradiatus (6), and Corydoras pygmaeus (1), C. panda (3), C. similis (3), and C. duplicareus (1).
Fish in the 90g are Paracheirodon axelrodi [the strain from Colombia] (11), Hemigrammus bleheri (7) and H. hyanuary (5), Hyphessobrycon rosaceus (6) and H. [formerly Megalamphodus] megalopterus (8), Nannostomas beckfordi (7), Papiliochromis altipinosa (1), Rhineloricaria fallax [parva]? (1), Otocinclus affinis (6), Aspidoras sp. [possibly albater] (3), and Corydoras leopardus (1), C. latus (1), C. metae (2), C. sterbai (3) and C. gossei (2).
