And I have an idea (especially when my car sell)... Hear me out. Walmart tosses away shelving, or even C&C is cheap and rather sturdy if you do it right... or even second hand stores have light shelving. Those are free or cheap, depending where I go... Tanks in petsmart, no lid, no light, no filter, are 10-30 dollars each for 5 gallons to 15 gallon LONG. =D
I found aquarium silicone for 16.00, large tube, And either craft mesh (they can see each other) or coroplast (yay!!! it's safe!! but stiff...) I can divide my tanks just right, safely. Since it is now summer, i can do this because the house itself will be 85-100 any day now. Petsmart may not give discounts or freebies (jerks...), but this store does, and PJ'S PETS might.
PJ'S PETS in west edmonton mall is THE WORST!! If dropsy was curable I woulda demanded that steel blue for free since he had spunk and the want to live despite being on death's doorstep.
