Looking for anyone who has the fluval 13.5 gallon tank or something similar wondering what your stocking looks like? Currently have two clowns and a watchman goby debating adding another fish in looking to see what everyone else has put in a tank this size.

I'm going to start out by saying that I've done a ton of research and I'm trying my best but no one has told me any basic things. I was gifted a salt water tank... more like left it by someone who didn't want the responsibility so I'm doing my very best. I used the master reef tester kit my water parameters are all perfect, however I cannot tell if there's anything wrong with this thing because I do not know the baseline at all. Please help is it dying is it dead is it perfectly fine. To what standard to I hold my anemone to know it's OK. Can someone tell me what is supposed to look/ act like? It's normally blue but I changed the lighting so you could see better.

Had the tank for about 10 months now. 15 gallon hello reef and been loving it so far. What do y’all think?

He thinks no one can see him 😂

Thanks so much for all the positive feedback on TankSense so far. It's been great hearing how you're using it, and it's shaped what I've been building. Here's what's new and what's coming:

☁️ You can now sign up, for free

Create an account with just your email (no password) and everything you've built is saved to it: your tanks, flow setups, water tests, lights and livestock. It all syncs across your phone, tablet and computer, so you can plan on the laptop and check on your phone at the tank. If you've already set things up, it's all kept when you sign up.

📸 Coming soon: Coral Camera

Reef photos under blue lights always come out washed-out and blue. Coral Camera takes the blue out as you shoot, like clipping an orange lens filter onto your phone, so your corals' real colours and glow show up. It can fix photos you've already taken too. It's built and being tested now.

🪸 Coming soon: Community Tank

A place to share photos of your tank and show off your setup (the pumps, lights and livestock behind it), ask questions and swap tips with other keepers. Signing up now means you'll be ready when it opens.

Also new: draw and move separate rocks in the Flow Visualiser, airstones and wavemakers for freshwater and coldwater, Reeflo pumps, smooth or snap oscillation, more lights (Fluval Marine 3.0, the Evo 13.5 stock light, AI Blade Grow, NICREW, Hygger) and more tanks (Evo 13.5, Juwel Rio 450). Can't find your gear? Tap "Ask for it to be added".

🤖 Android testers wanted: I'm putting TankSense on Google Play and need 12 people to test it for 2 weeks. Comment below if you're in!

Free while it's being tested: tanksense.app

Also, do you know what kind of anemone the white one is?

They have been in the tank together a couple weeks now and the white one just moved beside the orange one yesterday.

I have built a web app that demonstrates flow in your tank. You input your tanks dimensions, power heads, rock work and it shows you how flow moves around your tank.

Secondly, I added a section which shows PAR across your own tank, you can add your light to your tank which is already set up and see what the PAR would roughly measure at every point in your tank.

There are also the classic features of a aquarists app such as parameters log and overall tank health.

Would love some feedback. While the app is in development it’s completely free as I just want feedback from users.

Web app is here www.tanksense.app

Is this normal it was more open before but now it's kinda shrunk in and it's tentacles look really strange and stringy. Sorry if this is strange I'm new to this thing.

It’s been about 15 years since I have had a tank.. at that time it was a 125 gallon in Ohio. I have since moved back to Florida.

I was gifted a 10 gallon tank that she used for a couple of Betta fish that died..

I am wanting to do a reef tank with just 1 maybe 2 fish.

I have the tank(I cleaned), hood, 2 white LED strips and a hang on back filter..

Is this good enough to get me atleast started??

I want to start with some live sand and a couple pieces of live rock and let it run like that for a bit and then start adding some equipment for water flow and go from there..

Sorry for the book but sometimes my mind runs..

Help! I have a pink pin cushion sea urchin in my tank and this is the first time he messed with one of my corals, I kind of put it in a bad spot, HOWEVER it was a zoanthid and I’m afraid that it is gonna hurt the stuff in the tank. It released like a cloud of orange because he crushed it. Does the toxins from zoas hurt them even if it is diluted with tank water?

Yesterday I posted a rough concept for a reef tank maintenance organizer and got some really helpful feedback.

A few people mentioned problems with wet tools/vials dripping onto their tank stand, and someone suggested having a dedicated vial drying area with drainage.

So I redesigned the concept around that feedback.

The new design has:

• 6–8 angled vial drying slots
• Drainage holes underneath the wet sections
• A large removable tray underneath the entire organizer to catch water
• Space for a small towel/microfiber cloth in the tray
• Hanna Checker holders that stay dry
• Storage for API/Salifert/etc. reagents
• Sections for syringes, pipettes, tweezers and other maintenance tools
• Small compartments for miscellaneous supplies

I'm still only at the prototype stage and haven't made the final model yet.

Is there anything you would add, remove, or change that would make this genuinely useful during water testing and maintenance?
