Diana Test the water in the bag. GH, KH, TDS

Make the Q-tank match that. (GH, KH, TDS)

Then drip acclimate.

While the fish are in quarantine for about a month or longer make small changes to the GH, KH and TDS of the Q-tank until it matches the display tank.

10 neons, down to 8. Fish count also.

Lost another one. The others ate well last night.

I have a community tank with 2 angels (2-1/2 to 3"), 2 bleeding hearts, 2 Ottos, 2 glass cats, a 5" pleco and 10 neons. I have been reading that a pH of 7.0 is ideal for a community. Also, is my fish count maxed out for a 30g (I believe I am getting close). I want to add some corys to help clean the substrate.

kkoch Neatfish, my angels are not aggressive at all. I am thinking couldnt handle water adjustment.

Steveboos, my bleeding hearts only nip at each other. They leave all the other fish alone.

What do you think of my fish count and adding corys?
11-15-2012 02:36 PM
Steveboos You could even go a significant bit lower for all those species, but the whole issue here is consistency. It would be much healthier for your fish to just adjust to your stable high pH, then have to worry about the pH suddenly changing when a water change is done since your tank pH and tap pH vary so drastically.

I have kept all of those species at 7.6-7.8 and they are ok since it's consistent. But when i lowered my pH, their colors were slightly better.

And just a note, what out for your Angel's and Bleeding Hearts. Bleeding Heart Tetra's eat the fins and scales of other fish as a natural habit, so if your angels fins start getting shorter, we can narrow down who it is haha.

Had this exact thing happen with my 7 angels and Bleeding Heart Tetra's in a school of 22.

Neatfish Maybe your angles killed it?

Neatfish I lost a neon too out of the 5 I got from petco I did do a drip acclimation. I woke up to look at them and one of my ghost shrimp was eating it. Maybe it was a bad fish before I even got it.

Steveboos I agree that drip or slow acclimation is the only safe way to ad fish to a tank. You can never trust the store to have similar pH, some managers put TONS of Alkalinity or Buffer blocks in their tanks, put tons of chemicals in, or just don't maintain the systems like they should. All of this leads to a change in pH, Alkalinity, and Hardness, all which can kill fish very quickly.

Your pH is OK for Neons, not perfect, but they will adjust to it. If you want to lower it, add some driftwood for consistency, but to be honest, those fish are probably already used to a 7.4-7.8 pH.

Now the big question is next time you go into Petco, ask them to test THEIR water and show you. That makes a huge difference!

kkoch Got home last night and my remaining 9 neons were all alive. Yeah! They were hungry and added a colorful view to the feeding. Used my Master Water Test kit for the first time since purchase on Tues. PH was high at 7.6, Ammonia .25, Nitrate 10, Nitrite 0. Whats the easiest way to get the PH down to 7.0?

zzrguy I made a simple DA setup with a air line and valve it works good and I let the drip go for two or three hours or till I fill the gallon bucket 3/4 to 7/8 the way up. Then let the fish settle a little longer then feed them if they eat they good to go if not they are going in anyway but hunger.

james1542 It could very well be your water parameters, but you need to tell us.
before we can figure anything out.
But generally speaking, neons are sensitive, Petco has dead fish piled up on their filter intakes and their fish have likely been exposed to some pathogen thanks to their rack systems-so the odds are very much against you buying fish there.

chevyguy8893 Drip acclimating has made acclimating sensitive fish much easier for me. I bought 6 a while ago from petsmart when they were a dollar. They drip acclimated slowly for around 4 hours when the water volume was tripled. Haven't lost one of them. I do the same for GBR's and angelfish. I know drip acclimation isn't something everyone wants to do, but it works well and it is cheap to make. Although, it would be nice to have the in tank drip acclimation, so then there isn't a temperature drop . Also, adding a few drops of prime to the water during acclimation helps relieve some other stressors if the store doesn't add prime or something similar.

acitydweller Neons are one of those fish that are bred in pools by the thousands and heavily medicated against bacteria. They go though a heck of a lot before finally reaching our tanks.

Its good practice to get into the habit of acclimation, not to mention quarantine as they minimize the amount of stress on your livestock. Its more about being responsible for a living thing than doing what's convenient.

kkoch Lost one of my 10 new neons I put in last night. Probably will find more deceased when I get home tonight. Frustrating! Thank God they were only $1 a piece.

Blackheart Neons in general are very sensitive. I bought 15 from petco the other day, too, and it was only sunday, and now I'm down to 12.
