You know how sometimes you start something thinking it’ll be simple, and then three years later you’re explaining to your four-year-old daughter why we can’t just put any random rock from the backyard into the fish tank? That’s basically my entire aquascaping journey in a nutshell. What began as “let’s get the kids interested in something besides screens” turned into this whole thing where I’m researching water chemistry and my toddler has strong opinions about which piece of driftwood looks “more like a dragon.”
When we set up that first 20-gallon tank, I honestly thought you just bought some gravel, maybe a plastic castle, called it good. But then I started seeing these planted tank photos online – these incredible underwater landscapes that looked like tiny forests or mountain ranges. Real rocks, real wood, actual underwater gardens. I mean, people were creating entire worlds in glass boxes, and here I was with neon pink gravel and a ceramic diver.
My daughter was about three when I decided to try my hand at actually aquascaping the tank instead of just… hoping fish would be happy with whatever. I’d been watching these YouTube videos (during naptime, obviously) about using driftwood and rocks to create natural-looking scenes. The whole idea fascinated me – taking these ordinary materials and arranging them to trick your brain into seeing a forest floor or riverbed.
So we went to the local aquarium store – which became our new weekend adventure spot because my daughter loved looking at all the different fish and asking the staff a million questions. But this time, instead of heading straight to the fish section, we spent like an hour in the hardscape area. Shelves and shelves of different rocks and pieces of wood, each with these fancy names I’d never heard of.
The store employee was super helpful, explaining how Dragon Stone gets its name from the way it’s textured – all these jagged, weathered-looking edges that really do look ancient and mysterious. My daughter immediately gravitated toward it because, well, dragons. But he also showed us Seiryu stone, which has these cool gray and white streaks running through it that look like marble, and lava rock that’s full of holes and incredibly light.
What I didn’t realize (and learned the hard way) is that different rocks actually affect your water chemistry. Some stones will raise your pH, others might leach minerals, and you need to know what your fish can handle before you start building underwater mountain ranges. I spent one very stressful weekend dealing with cloudy water and confused fish after adding some limestone without researching it first. Live and learn, right?
The driftwood selection process became this whole family affair. My daughter would point to different pieces and announce what they looked like – “That one’s a sleeping dinosaur!” or “This one looks like the tree from our backyard!” She wasn’t wrong, either. There’s something about weathered wood that makes your imagination run wild. Pieces that looked boring sitting on a shelf would suddenly become the backbone of an entire underwater forest once you got them home and started arranging them.
Getting the wood ready was its own adventure. You can’t just drop it in the tank – it needs to be soaked and prepared, sometimes for weeks. We ended up with buckets of soaking driftwood all over our patio, which my spouse was thrilled about. The wood releases tannins that turn the water tea-colored, which isn’t harmful but looks weird if you’re not expecting it. My daughter thought the brown water was “like chocolate milk for fish,” which… okay, sure.
Actually arranging everything in the tank became our biggest collaborative project yet. I’d read about composition techniques – using the rule of thirds, creating focal points, building depth by placing larger items in back and smaller ones in front. But my daughter had her own ideas about where the “dragon rock” should go and which piece of driftwood would make the best “fish apartment building.”
We compromised. I’d handle the technical stuff – making sure rocks were stable and wouldn’t crush fish, ensuring there were proper swim paths, checking that everything was firmly anchored. She got to be the creative director, picking the final placement and deciding which areas needed more “decoration.” Her eye for color and balance is actually pretty good, probably better than mine honestly.
The whole process taught us both so much about how nature works. We talked about why rivers carve rocks into smooth shapes, how fallen trees create shelter for animals, why certain plants grow on certain surfaces. My daughter started noticing similar patterns when we’d go to actual parks or hiking trails – “Look, mom, that rock has holes like our lava rock!” or “The moss on that log looks just like the moss in our tank!”
One thing nobody warns you about is how addictive collecting hardscape materials becomes. I started bringing home “interesting” rocks from everywhere – the beach, hiking trails, even the landscaping at the grocery store (don’t judge me). Each piece seemed to have potential for some future aquascape. Our garage started looking like a geological museum, with buckets of rocks organized by type and size.
My son, who was barely two when we started this whole thing, couldn’t really help with the technical aspects, but he loved the sensory parts. Touching different textures, watching me rinse rocks, “helping” by moving small pebbles from one container to another. He’d babble at the tank while I worked, probably giving his own artistic commentary that I was too focused to appreciate.

The educational value has been incredible. My daughter now knows the difference between sedimentary and igneous rocks (sort of), understands that some materials dissolve in water while others don’t, and can explain to visitors why we chose specific pieces for different areas of the tank. She’s developed this vocabulary around design and natural processes that I definitely didn’t have at her age.
We’ve experimented with unconventional materials too. Found some smooth pieces of glass at a craft store that we added as accents – they catch the aquarium light and create these cool reflections. Tried some ceramic pieces designed for aquariums that looked like coral or abstract sculptures. My daughter was fascinated by how the same materials could look completely different underwater versus in air.
The maintenance aspect has become part of our routine too. During weekly water changes, we’ll rearrange smaller rocks, clean algae off the driftwood, sometimes move decorations around. My daughter calls it “redecorating the fish house,” and she takes it seriously. She’s noticed that certain fish prefer certain hiding spots, so she’ll advocate for keeping their favorite areas undisturbed while changing other sections.
Setting up our second tank (the 10-gallon in her room) gave us a chance to try a completely different style. While the main tank ended up looking like a forest floor with lots of wood and green plants, her tank became more of a rock garden theme with carefully stacked stones and more open swimming space. She wanted her guppies to have a “dance floor,” which I thought was pretty thoughtful.
The whole experience has changed how I think about design in general. My graphic design work has probably improved because I’m more conscious of composition, negative space, visual flow – all concepts that apply whether you’re arranging rocks in a fish tank or elements on a website. Plus, having these hands-on creative projects helps balance out the screen-time aspect of my job.
Looking back, what started as a simple attempt to give my kids some nature exposure has become this ongoing family hobby that touches on science, art, responsibility, and creativity. My daughter talks about being a “tank designer” when she grows up, and honestly, watching her problem-solve spatial relationships and think about what different creatures need to be happy… she might be onto something.
We’re planning our fourth tank now – she wants something with “more caves and secret places” – and I’m letting her take the lead on the hardscape selection. She’s got ideas about using multiple types of stone to create this elaborate underground city concept. It’ll probably be ambitious and complicated and might not work exactly as planned, but that’s kind of the point. We’ll figure it out together, one rock at a time.
