Black Neon Tetra Have Black Spot

Hi, so this black neon tetra os newest one and I just did notice this black spot on her side. I did dose voogle immunity buster and that's all. Parameters are fine. What this could be? What should I use?
This is best picture I can get because it is fast fish and moving all the time.


Please I need help fast in two days I am going on 2 week trip and I am leaving aquarium care to my sister

 

Can you get a clearer picture?

Is it just a spot, or does it look like the scales are messed up too?

Can you get a clearer picture?

I tried for 30 minutes no way I can get better picture. No it doesn't look like scales are messed up and it isn't a bumped out. It looks like it is inside or on surface if I look at it other side I can see light black inside but not on skin if you know what I mean.

Maybe this one is better

Looks to me like just part of the fish's color but I'm no expert. At this point, since it's not bumping out or scales are fine, I would be more worried about the algae on the plants. If you can get your plants to optimal health your fish will usually be fine as long as water quality is good.

 

I also wouldn't worry too much about the spot now either. You don't want to throw meds at it without having a better idea of what it is, so just keep water quality good until you're gone. It wouldn't hurt to do a few extra changes.

Can your sister do water changes while you're gone?

Yea I am battling algae problem since I starr adding micronutrients so I am trying to find good balance between micronutrients, liquid co2 and for now I am not adding any macroelements because reading of nitrate ect is just fine

Yes I will do wc today I did one 4 days ago and she will do two 35% wc while I am not here. She will not do to much vacuum cleaning but at least water and what she can see cleaning will be fine and probably little less feeding than usual just to be safe.

Honestly, the liquid co2 is only going to help a small amount. The best way is to use pressurized co2. Its really not as expensive as people think often cheaper than a cheap hob filter. My 10 lb. tank was only around $40 filled. You can get the tubes and defuser and everything on Amazon for real cheap as well. I think I paid a total of $50-$60 for everything I needed for pressurized. And depending on how small the tank is it is much cheaper. I have a 55 gallon.

 

You don't need injected CO2 to have a healthy, well planted tank without algae though.

Apparently flourish a liquid fert you can buy from the store has been known to kill algae? How long do you leave the lights on the tank for?

Oh wow, I'm in the works of making my own DIY co2 system, is it true you need like a water flow to blow the Co2 bubbles away before they diffuse on the surface? Apparently once it hits the surface its rendered useless, so where would you place the Co2 nozzle near your filter? How long does the pressurized from last for though is my real concern, I have lemons that grow endlessly in my backyard so I can use that to somehow make Co2 idk haha

I know it isn't that expensive and I am planning to buy it in 2-3 months, but at this moment it isn't in my expense limit.

I was suggested to use it until I get real co2 so I am using it from start just trying to get real dose. I use easy carbo 1.8ml daily and profito (micronutrients) 0.4ml every other day.

I have lights on for 8 hours from 13.00 to 21.00 and glass is covered in the morning. I don't have soil but jbl KUGLEN /BALLS IN gravel.

A powerhead is recommended. I would put the defuser somewhere below that so it is blown around the tank and the bubbles stay in the water for as long as possible. Good flow is healthier for a tank no matter if you use co2 or not. Most fish like the Current and will be healthier as well.

Oh yeah I do have good flow its just I have an air pump and not a filter so all the flow is just bubbles essentially, a powerhead huh? I thought they were for salt water Aquariums? I might just stick a small filter head below, thanks for the help!

Yep totally agree with you on that one I'm really sorry.

You don't have a filter???? Are there fish in the tank????

Just to say I have two inside filter. One pat minI and one juwel bio flow one. 400l/h and 300l/h diagonaly standing in 85l aquarium so water flow is great.

Eight hours isn't that bad. Hm maybe you could start employing some biological warfare against the algae, ottos I heard do a good job and you should definitely try shrimp, I like to use an like the aquarium wall scrubber to scrub algae off my walls and dump the head of it in my shrimp tank and they love to feast off the algae. So Shrimp and ottos I know should eat the algae off your plants. : )

Oh no sorry to clarify, I have a DIY filter now cause my main filter was failing so I took all its bio media and stuck it in a bottle with an air stone below it, so the water doesn't per say travel horizontally but rather the bubbles just go straight up.

I have male apistogramma in tank so sadly no shrimps for me. I have two nerite snails. And ottos are in plan but not for two three weeks because lfs doesn't have them in this moment.

Hm ok, maybe try using root tabs instead so the algae can't access the nutrients, also try lower down your lighting a bit and use your finger to remove some algae off the top leaves where the plant gets it's most light from. Cutting off your carbon dioxide too might help as plants don't necessarily Need that they just do better with it, so maybe cutting it off till the algae goes away might help. All your plants listed in your bio seem very hardy, I think what you need to do now is to ensure that your plants are Out competing the algae, cause most of your plants listed are root feeders root tabs should do the trick in isolating nutrients from the algae.

I did put jbl clay balls mainly with iron in itself. So that's done. I am removing algae and injecting some carbon directly on algae and they die off after that. All plants are growing but algae are growing too. How much of micronutrients and carbon should I add?

Btw. I didn't update plant list for some time, so but almost all are hardy.

 

Plants do need carbon dioxide, but the liquid additive/substitute is not needed by the plants (as it's not real CO2). The liquid additive should not be helping the algae grow though.

Oh, ok. You had me going crazy for a minute.

Lol, I wouldn't blame ya. Thanks for the info tho!

Oh wow, I didn't realise it was liquid Co2 I retract my statements about stopping it then.

 

I have black neons and some do occasionally have a spot of color. My favorite one, Bully, had a discoloration similar to yours, and it was just that, a discoloration. So most likely your fishy friend is OK. Just keep an eye on it.

I wouldn't be concerned if it was just white spot but it is white with black inside

You wouldn't want to discontinue injected CO2 either.

I would target it at the algae, but I would aslso add root tabs for the root feeders, as mentioned, manually remove the algae, reduce lighting and/or add in a siesta period, and do frequent water changes to help remove it.

Root tabs are all ready in so mabey to try 7 hours of light while I am at trip
