Water Changes – Refilling the 150

I love watching my 150 gallon tank during water changes. As I add water back into the tank, the fish go crazy, swimming through the bubbles and schooling tightly. My gold barbs group together, swimming throughout the tank in a hug pack. Here are some shots of the tank during the refill that I liked:

I used to use Seachem Prime during all of my water changes. If you don’t use this stuff, start! It works wonderfully, and a single bottle lasts a long time. For my 150 gallon, because it is so large, I began using Seachem Safe. Safe is just a concentrated powder version of Seachem Prime. Both are phenomenal products that have made my water changes easier. They also can be used for emergency situations, like ammonia spikes.


When doing big water changes, it is much easier to be able to add the new water right to the tank from the faucet (as opposed to individually treating buckets and pouring them in). To the tank being filled, add enough Prime or Safe to treat the full volume of the tank, then refill the tank with tap water as usual. Of course, if your tap water isn’t acceptable for water changes, this process won’t work well for you.

Ludwigia Repens Deficieny – Now Recovering



Finding the right balance in a tank between the plants, fish, and everything else can be a difficult task. For me, I have recently found that I wasn’t adding nearly enough nutrients to support healthy plant growth. The ludwigia repens seen above is a good example of my tank beginning to bounce back after a nutrient deficiency. The yellowish leaves with holes in them were the original tops of the ludwigia less than a week ago. Since I started dosing with more nitrates (via dry KNO3) and Seachem Flourish, in addition to continued use of Seachem Flourish Excel (for liquid CO2), everything in the tank has begun to grow quickly again with bright green hues.

Victory! At least for now… Hopefully they keep it up!

Ghost Shrimp

Regal as Fuck

What are listed as “ghost shrimp” in stores are not always actual ghost shrimp. Many shrimp belonging to the Palaemonetes genus get generically labeled as ghost shrimp by inattentive sellers. The Palaemonetes paludosusĀ is what is typically considered to be the ghost shrimp, also known as the American Freshwater Glass Shrimp (or a variation on such a name).

I’m a big fan of ghost shrimp for the following reasons:

  1. Price – They’re usually less than $1 each. Sometimes my LFS sometimes has them for only 17 Ā¢.
  2. Resiliency – I’ve only lost significant numbers of ghost shrimp from two causes: whisker shrimp and gassing my tank with a faulty CO2 regulator. They do fine in temperatures from the mid 60’s to mid 80’s on the Fahrenheit scale.
  3. Food – They make great food for larger fish and puffers (though dwarf puffers are probably too small to eat them full grown), AND they eat pretty much any debris in my tanks. A crew of ten or so in my 15 gallon keeps it spotless. I almost never need to vacuum it thanks to these guys. Plus, since they’re basically transparent, you can watch them change colors depending on what they’re eating. This also lets you know what they prefer to be eating.
  4. Aesthetics – While often overlooked, ghost shrimp can develop some fantastic coloring. My old guard last for about a year before a CO2 incident killed them. By the end, they were covered with small red and blue highlighted markings. It’s also nice that they don’t force themselves into the forefront of the tank. The fish and plants can still be the centerpiece, but the attentive tank owner still gets the joy of seeing these shrimp grow and color if they want to take the time to do so.
  5. Breeding – So long as you have at least one female and one male, they will find a way. The female carries the small green eggs in her saddle like many other types of shrimp. So long as there is cover, some of the little ones usually find a way to survive. I manage to have growing numbers of ghost shrimp in a tank with four female bettas, who gladly devour a small shrimp if they can find it.


The only real downside to these guys that I have run across is that they are carnivorous. If they can, they will eat other, less aggressive or smaller shrimp. So if you want to start with ghost shrimp then transition to red cherry or other such varieties, it would probably be best to remove the ghost shrimp first. This aggressive behavior is also what allows them to live with bettas, which red cherry shrimp typically cannot do.

Here are some pictures of my ghost shrimp:
