Reddit mentions of LILYS PET Stainless Steel Aquarium Tank Aquatic Plant Tools Sets (5 in 1)

I had a big gap in fish keeping and dug up the ol ten from the basement myself at one point. There is a lot of info avail to you at the top of the Sub, in the Wiki. so, here's a few things I can share that you had questions about:

• So, your tank isn't cycled if it has any ammonia or NitrItes (there should be NitrAtes/always keep below about 30 ppm)
  
• A pleco needs a larger tank and way more filtration than you have unfortunately. Here's their profile I think it may be a 20 high (?) as the minimum, not sure several inches longer than a 10 in any case. And since they eat all day long, they poop all day long, so are high bioload fish/messy/big poopers... you might want to think about rehoming him (after he eats the fungus on the wood lol--completely normal and goes away btw). He makes your tank overstocked. You can punch everything in Aqadvisor.com and see what it gives you for stocking but make sure to look at the Filtration Capacity Percentage which is probably the most important thing. Keep as high as you can to help your tank parameters be as healthy as possible. I try to keep mine at 200% if I can depending on the tank.
  
• Don't be scared of real plants. I have sand too. No problem. Get a pair of the long aquascaping tongs. I wouldn't even bother with the other tools frankly, but if you want to, get a set like this (I did research they are great and don't rust). But, I did just order this because I broke one of my tongs after years of abuse lol. If your light is full spectrum, get whatever plants you like for the most part, but if it's not, get low light plants like Sagittaria subulata, Anubias, Java Fern. You can also add API root tabs to the sand if you ever need to or Seachem Flourish for water column feeders as a fertilizer.
  
  I totally just realized I read your post wrong. You don't already have the Betta and Neon Tetras. In that case, I would skip the neon tetras as they tend to have a lot of problems probably because they are sooo popular and in demand they get overbred/inbred, poor husbandry in breeding practices, etc. I don't know.
  
  
• The size of the tank has nothing to do with whether a Betta is laid back or not. Each Betta has a different temperament. And like the other person said, you do have to be prepared to rehome either the Betta or the fish you chose to home with him becuase it does not always work. IF you decide to do a Betta with ANYthing else in the tank add the Betta last so he doesn't see them as invading his space. But, the only fish that I would give it a try with in a 10 gallon would be Ember Tetras really. You could do 6 of them and after they've been acclimated and intro'd to the tank, then do the same with the Betta.
  
• Also until you move out the pleco, go grab a bottle of Seachem Stability and add it to the tank for a week since you have a fish in there already. If you skipped the other fish, you might be able to keep him and just have the Betta, but you'd have to double check on that first. Look up on the profile I gave you for SF as it's the most reliable site for that type of info.
  
  Welcome back and good luck!

I have a kit similar to this, I think I got the 4 tools for $10 somehow.

Tweezers, both large and small, are critical for planting.

Curved scissors help tremendously.

Flexible pipe cleaner for cleaning out all fittings, pipes, filters. Also is great for shooing fish / shrimp out of corners without hurting them.

If you’re lucky enough to live on the west coast, I really recommend a visit to TAP Plastics- they have all the scrapers, tiny containers, large containers, needles, vials, boxes, and spray bottles that you could ever need. Also, every piece is like 37 cents.
