Rosy Barbs loosing color
 
So my rosy barbs are starting to loose a bit of their color. I have changed a few things in the tank recently and was hoping someone could point to something I have done or could do to help them. The tank is 38 GL.
I changed my substrate from gravel to sand, and also changed from a medium air stone to a 10" air wand that is on the back of the tank. I keep the wand to one side of the tank to reduce current for my gourami on the other side. Is the 10" wand large enough? Is it possible the fish aren't getting enough O2?

I am also in the process of planting my tank. I just changed the bulb to a 24" T5 bulb for plants. The previous bulb was what came with the tank. Would that put a change in the fish's color?

Their current diet is flakes twice a day, and blood worms once a week. Should I change up their diet? Is there something else I could give them to improve color?

Thanks for any tips!

Did you check out the Rosy Barb profle at the top of the page under Tropical Fish Profiles?

It could be diet or stress from not being in the right numbers that are causing the paleness. They also do well in somewhat cooler temps than most community fish.

What kind of filter are you running, how did you change out the gravel, are they eating acting normal. New Life spectrum small pellets are very good for color.

I've read the profile and the barbs had been doing very well, and their behavior is normal now. they are swimming and eating like normal.

The temp usually stays in the mid 70's. once the weather cools off it won't be hard to maintain a little lower temp. i'm not sure how I can lower the temp in the meantime.

I'm using a Marineland Penguin 200 for a pump, and recently changed the filter.

To change the gravel, I put the fish in a bucket with water from the tank, and drained the tank. I removed the gravel then added the rinsed off sand. I then filled and treated the tank with new water, and added the fish with the bucketful of the old water. The water has been clear, and no other fish seem affected.

I'll check out the Life Spectrum pellets. Is that something I should be feeding them in place of flakes, or as a supplement?

If you took out the gravel and drained the tank you might have started it to cycle again did you put your same filter back on with the old media in it . Do you have a test kit for the water. I would keep an eye on it for awhile. NLS is a staple diet I very rarely use flakes sometimes as a treat lol:-)

Agree, monitor ammonia and nitrite, there might be a rise in both. Live plants will help with this. At on the bubble wand, when you get live plants, that should go as it will drive needed CO2 from the water.

thanks for the tips, i'll keep an eye on my levels and do water changes as needed.

as for removing the O2 wand, is there a good sign that it is time to remove it and let the plants convert the CO2? I'm adding plants in slowly, mainly because I want to see what my fish will/won't eat, and because I've never had live plants and don't want to bite off more than I can chew too fast.

I would remove it now. Plants need carbon, it is a macro-nutrient, and occurs as CO2 for most plants. But CO2 is slower for plants to assimilate from water than air, so any device that dissipates it from the aquarium is likely to be detrimental. CO2 occurs from the respiration of fish and plants, but more comes from the breakdown of organics in the substrate by bacteria. The level of CO2 in a moderately-stocked tank is therefore not going to be great. Carbon can easily become the limiting factor in plant growth, and this leads to other issues like algae. So, keeping it in the tank as much as possible is a good maxim.

I just added a few more plants and turning off the wand. I'll keep an eye on the fish and make sure they aren't gulping for air at the top. They are my top priority over the plants. Thanks for all the tips!
