My initial comment was intended as a bit of a joke. I admit; it is very easy to lure me into a debate (I took a lot of Philosophy courses back in university), but no hard feelings on my end anyway.Bred wrote:Flusher, let's not get into a fruitless semantic argument.
Nope - I'm not committed.Bred wrote:You have committed to those tank sizes and you have committed to those species and by all means, go for it.
These tanks may house my amphibians in the future, after I build a new tank. Like I said:
"I'm already working on a tank upgrade..."
Even if I don't upgrade, "grossly cramped conditions" doesn't quite describe any of the tanks I've kept these puffers in (given their size at the time, at least).
I might convert this tank rack into a coldwater set-up for my ACFs, if I can find something suitable to put in the other tank. Because of the overflow plumbing, the water level has to be high, so I'm going to look into a totally aquatic newt or something of the like.
On the other hand, these two puffers don't swim along the glass sides nearly as much as most of my other puffers. They seem content staying more in the middle of the tank. So, I'm not in a rush.
It was actually really easy to make the stand and the tanks. I designed a few stands, conferred with some local hobbyists about structural integrity, settled on a design, then slapped some 2x4s together with plenty of screws. For larger, heavier tanks, the design would definitely have to be upgraded for support.Bred wrote:Slightly OT, I'm very curious to hear about the construction process of these tanks. How tough is it to make a tank? Did you get the glass precut, and what are you using as a frame? Any pics you can offer? This is a project I'd like to learn more about approaching.
I had all the glass custom-cut and drilled, bought some aquarium-safe silicone, then assembled them and installed the overflow bulkheads. (I could only find white silicone; the clear stuff looks better.) I used a razor blade to trim off excess silicone once it had cured.
The bottom glass panel has to be the full tank size (outside dimensions of the footprint). The front and back panels are the full length, and the full height minus the width of the glass from the bottom panel. The sides are the same height as the front and back, minus the width of the glass from the front and pack panels. (You have to remove the widths of the glass to ensure a snug fit.)
Working with silicone can be messy. It takes some practice, but it's pretty much fool-proof to get a good seal if you use lots.
The tanks don't have frames, but there are 2" strips of glass on either end at the top of the tanks for added strength. (For longer tanks, a thicker glass would be placed across the width in the middle of the tank, too.) For an unframed tank, it needs to sit evenly on styrofoam. I use 1/2" pink insulation foam - it's thinner, cleaner, and seems to work just as well as the thicker white styrofoam.
After installing the bulkheads, I painted the back panels black. After putting the tanks in place, I added some swinging wood panels to block the light above the tanks, and I put some little doors on the bottom of the stand. I'm thinking about giving the stand a good sanding, then either staining it or adding more decorative wood panels for a more finished look.
Here are some photos.

I had just added the sand before taking the picture, so the water was cloudy for a day or two.
I'm not comfortable with really deep substrate. It's too hard to maintain (gravel siphons and sand aren't a great match), I'm a bit worried about anaerobic spots, and I've watched these puffers bury themselves. They don't dig vertically, so I don't think they need 6" of sand. 2.5" seems like enough. That being said, I'm very comfortable with the water depth. Eyeballing what these puffs will be at full-size, I think double their body length in water depth is sufficient. That's about what I've got.Bred wrote:/also - I'm still not sure about those tank heights. All I can say is try it and let us know what you think.
//also also - Be sure to cover the tanks well - we don't want any jumpers!
Yes - covers to prevent jumping is one of my priorities.
