Reddit mentions of Lee's Betta Keeper Large w/Lid, Gravel and Plant

Lemme tell you about my fishkeeping experience.

Elementary School

I won a goldfish and a painted fish bowl at a local museum fundraiser. It stayed in my grandmother's car while we went to a birthday party afterwards - she encouraged me to just leave it in the shadows. It was summer in south Mississippi, so it was in 90+ degrees in a closed car for 3 hours. She tried to revive it by blowing bubbles at it with a straw. It didn't work.

Its bowl survived, and I kept a few betta in it over the years. One of them jumped out the night we got him, which in retrospect, was probably the kindest death he could have had. Another jumped out and was found alive, but very dried out, on the carpet. Grandma tried to revive him too. It still didn't work.

Middle School

After several betta suicides, Mom suggested I get a tank with a lid. I got two. Meet the Dual Betta Hex. Oh boy. Where do I start?

• Yes, I used the gravel that came in them.
  
• No, I only sometimes used the godawful spiky plant. It uprooted itself too often for me to use it all the time. So oftentimes, my betta went bare-tanked.
  
• Yes, I had four bettas. One died after like a week, FOR SOME REASON. I removed the divider and patted myself on the back for Mr. Moomoo, the survivor, having such a big and comfy home.
  
• Yes, I cleaned it with dish soap... and again, patted myself on the back for taking such good care of my fish. They lasted SIX MONTHS. SIX WHOLE MONTHS! Betta are only supposed to live, like, two!
  
• Yes, I thought they were thrilled to see me. Really it's because I shook their tank until they "woke up". ^Oh ^^my ^^^God.
  
• Yes, I had dreams of being a rich woman one day and being able to afford a table-full of these torture chambers... after all, they stack and lock via ridges on the lids and bottoms, and what's better than four sick betta? That's right, a few dozen! (bleh)
  
  I also kept some fire-bellied salamanders in those contraptions. Poor things lasted maybe a month.
  
  High School
  
  I eventually saw the error of my ways in late middle/early high school and upgraded... to a 1 gallon tank, pretty much exactly like this. A vast improvement over two betta in half a gallon of water (why...) but still unheated, and the undergravel "filter" was a joke. I stopped using dish soap, more out of laziness than out of knowing you shouldn't, but sometimes was "nice" to my betta and gave the tank a good soapy scrub. I had a dwarf frog for exactly one night and returned it to PetSmart the next day for a full refund. At least this time, I had a proper silk plant instead of some fin-ripping monstrosity.
  
  College
  
  Enrolled in a marine biology program (because I love fish... yes, even though I didn't know jack about keeping them healthy) I went all-out and had an 8 and 5 gallon tank, properly equipped, filtered, heated, and maintained, for pretty much just betta. One of my betta lasted two years, got visibly sick one day and nothing I did helped him. He slowly petered out on the bottom of his tank over a month. The other lasted nearly 5 years, 2 of which were in my inexperienced and not-really-caring mom's care (I had an unexpected cross-country move) where the tank got cleaned once a year when I'd come home to visit.
  
  Graduate School
  
  Right now, I have a Fluval Spec V here beside me that's getting a dry-start dwarf baby tear carpet planted tomorrow. And its planned livestock? A betta. In a nano freshwater tank, they're all that really thrill me. Keep your scarlet badis, keep your red cherry shrimp, keep your rasboras, betta are my jam.
  
  Maybe I'm overcompensating?
  
  TL;DR: Betta holocaust. I got better.

I got five of these individual tanks. There's a small clear divider in the middle that's removable. I took the divider out and each girl got their own tank during the first week for quarantine. They're just shy of about a gallon of water capacity.

I had them all lined up so the girls could see each other during quarantine week. After the first day they all stopped flaring at each other.

I acclimated them to the main tank's water and temperature by slowly replacing the water in their individual tanks with water from the main tank.

I then bought a floating fish breeder box and started to put the girls into the main tank. Least agressive first to most agressive while rotating them in and out of the breeder box before releasing into the main tank. There was about 15 or 20 minutes between each rotation, just long enough for me to observe the girls in their new environment behind the plastic keeping them safe from each other.

My guess is that since they'd been seeing each other for a week in a similar fashion they pretty much ignored each other once they were all free in the main tank together. Spent most of their time exploring and picking their own spots. About five minutes of chasing while they all played musical plants and then harmony from then on.
