25g tank, work in progress

Recommended Posts

Since my 27 liters tank was becoming too little for my impulses, I went ang got another tank. This is actually the biggest I ever got (used to have a 20g peninsula).

I went with the 25g peninsula from Waterbox because I wanted a AIO tank between 15 to 30g and it perfectly fits on my desk at home.


The setup :

  • Tank : Waterbow peninsula 25 mini
  • Return pump : aqua medic 1.3 (I wanted something dead silent, I wasn't disappointed)
  • Light : AI Prime HD
  • Wavemaker : jebao SLW 10
  • ATO : some mechanical cheap thing
  • Filtration :
    • filter floss + carbon in chamber 1
    • biomedia + chaeto in chamber 2
  • Heating / cooling : 200w unbreakable heater and desktop usb fan both on Inkbird controler




The cabinet unded the tank holds the food, towels and all the little I need for maintenance. Everything is plugged in on another cabinet.

The ATO tank is around 20 liters.




Current livestock :

  • Frostbite clownfish
  • Purple euphyllia ancora
  • Green euphillya paraancora
  • Red and Green lobophilla
  • Rainbow acan
  • Red rodhactis
  • One pissed off goniopora
  • Gold leptoseris
  • Phoenix montipora
  • Some zoas  that I hope to turn into a zoa garden
  • Snails and hermits


The rockscape is pretty simple and made of 3 rocks. 

The sand layer is really thin (transfered it from my 27 liters tank). I currently like it as it is.

The tank is currently hitting th beginning of the ugly phase on the "new" rocks. They are only a few weeks in.


I ordered some snails, the CUC should be strong enough to take care of the algae. Should be here next week.

Also got :

  • a new euphyllia
  • 2 more fishes to befriend the clown 

I don't plan on adding more fishes after that,

Thank you!


My order was delivered today. That new hammer is really yellow (bottom left), I hope it will acclimate nicely to the tank.



Half the zoas are looking pissed...can't figure out why. The Sunny D's were looking great and now they are...different.

Sorry for the qualité but they keep Moving around. Here are the two new fishes I got last week :





The dragonet is still a baby but it's captive bred. 

My zoas are still looking like sh*t. I started to feed more heavily so my nitrates and phosphates go up. I don't test but I know the current bioload of the tank is still low compared to what I used to run in the 20g.


My clown is still in the small cube, I will put it black in the 25g next week. It should be less territorial.


That euphyllia is acclimating slowly. I will have to think of a place where to glue it.

  • 4 weeks later...

Current state of the tank :



  • Zoas are still looking ugly and some are probably going to die. Never had this many problems with zoas before. 
  • Rest of the corals are happy (except the caulastrea, but it looked like that when I got it. Let's not mention the gold hammer, I kinda dropped it while trying to glue)
  • The good news is that Harvey the clownfish is finally behaving nicely

It's now time for growth. I probably won't change anything in the next 3 to 4 months.
