  1. Unlikely, IIRC the answer to this quesiton in the past has been that the Co-op already prices it's products low to be a good value and it's not a part of their sales strategy. The deals to be had are in the members section of the site, and those seem to come and go pretty quick.

    On the plus side every day is Black Friday at the Co-op, no FOMO.

  2. Like Andrew said I think it's all environment too. Freshwater fish have the capacity to have awesome colors, and some US natives do even in the wild, I.E. sunfish can have amazing elcectric blue colors, orangethroat darters can have nice orange and blue markings, southern redbelly dace have beautiful gold stripes and vibrant red bellies especially in breeding colors. IMO it's all about the selective pressures in the environment. If sunfish survival was made better by being solidly electric blue they would be. (breeding project anyone!)

    All that said there are plenty of drab colored saltwater fish too.

    what plastic do you use? I have a friend that wants to 3D print me a decoration for a tank but i want to make sure its safe.

    In general just about any PLA will be safe, I have used various PLA's in my aquariums for many years and it's never caused any issued for me. My favorite high quality filament for a while now has been Fusion Filaments HTPLA+.

    I live on the third floor of an apartment building and currently have a 40 and a 20 set up in the spare room of the apartment. I was thinking about setting another 40 up in the same room. At what point should I be concerned about weight being on the third floor?

    Ive seen loads of conflicting information online so I wanted to ask yall what you have done.

    I can lend a little info, I do structural engineering for a living. For a long time and even today residential in the US is designed for 40-psf without requirements on concentrated loads. For reference office space is designed for 50-psf with a requirement of a 2000-lb concentrated load, the logic being in office settings it's not uncommon for a heavy copier machine to be in the middle of the room. For residential like apartments, heavy things like big furniture and aquariums are typically placed near walls where the floor framing is near it's support so heavy loads aren't as big of a deal.

    Now it isn't always a geat out of jail free card putting tanks against walls since if the floor framing runs parallel to the wall the framing under the tank may not be near a support. Unfortunately it's not always a clean cut answer without some structural investigation and or a quick beam check, but in my experience when I worked for a small firm and would on rare occasion get calls about aquariums they were never an issue.

    Also there is some safety in that typical structural design is for things to bend before they break, so if you start to notice new deflections or other structural stress you know you're taking it too far.

  5. @Sarina So glad you are here, I'll be following this thread for the learnin's 🙂

    I would love your thoughts on PLA within the context of 3D printing & aquariums, as my experience with it goes against it degrading with water. I have tried over years to see if it degrades in aquariums/ponds and in soil with no noticable effects to structural integrity or even finish. I've read no name brand PLA's aren't always consistent, but even with no name tests I haven't noticed any degredation. Google diving has lead me to believe the idea that although PLA is bio degradable, this only occurs at high temperatures (145F-ish) and in the presence of certain bacteria. I am very interested to hear your thoughts on this.

    Also I would love if you would take a look at my favorite filaments data sheet and comment. Thanks! -> Datasheet

  6. So I just wanted to shoot this out there. Over the years as my knowledge of gardening and fishkeeping has grown by study and testing I'm wondering if others out there have tried using fish food as a fertilizer and noticed objective results?

    I know it's pretty difficult in gardening to test confidently in one season unless you're very strict on controlling soil, sunlight, plant genetics, ect. As I have learned it isn't fair to judge a tomato in one season as a hot or dry summer can effect flavor ect.

    I'm asking since I have aquired a sizeable amount of food that either is super old or my fish don't like it, other reasons, ect, and in spring time I plan on tilling it into my garden bed to add organics and fuel the life in the soil that in turn fuels the plants that feed us.

    I would he happy to hear any experinces with this. I have only tested it once in a potted plant. Which was successful but that's hardly data. But... the plural of anecdote is data. So lets see what we all have experienced. (❛ᴗ❛)

  7. My experience with them is I got a random pair on plants in 09 and the colony that came from them was plain brown and brown with the lepoard pattern. After a few years I started getting some copper and after a few more years I started getting the blue variant. The population slowly shifted to mostly blue and a few years ago I removed all my brown snails from the colony and since then I have yet to get another brown. Currently all I have are the blue and blue with some leopard patterning.

    My guess is the brown only holds due to selective pressure in the wild and currently in my colony I'm thinking about removing the leopard pattern in a try to get as close to colorless as I can get. I have never had a pink body one though, only the dark body morph.

    I'm not aware of a product that meets all of what you're looking for atm. My personal way of doing things is I like to use 18650 battery chargers that also have a power bank feature. That way I can vet the batteries and I have full control of the batteries that go into it. I can move or replace them if they go bad or if a power outage is extra long. I have good things to say about the Nitecore F2 Flex, Xtar PB2S, and the Efest 4213 LUC V6.
