Hi everyone I am having trouble with my new tank, I had no choice but to aquire all of my fish at the same time because I adopted them from a lady who could not care for them any more.

I will explain my whole setup and type of fish:

I have a 55 gallon all-glass setup with an aqua-tech 30-60 over hang filtration system (very soon we are getting a fluval or eheim-which is better?), 50 pounds of black gravel, about 15 fake plants and a beatutiful giant castle in the center. I have one heater that works very well, and the tank is with just stock lights.

Now the fish I have in there are:
approx. 15 guppies 5 of which look pregnant
6 zebra danios - 5 of which were bought at petco and petsmart (3 petsmart 2 petco the one that passed away would have made 3 from petco)
1 full grown dwarf gourami
1 3 inch blue gourami
1 4 inch plecostomus
2 3/4 inch chinese algae eaters

so I know my filter needs to adjust and such and my ammonia levels are a little high, I have been changing 1/4 of the water while cleaning the gravel every day for a few days now to try and help this. When I change the water I wait 15 mintutes and add benificial bacteria to the water as directed. 5 ml per 10 gallons, which is about what I change, a little more than 10 gallons I would say. Like 15 gallons.

I have also slowly been adding the salt that has been reccomended that I do, about 1 tablespoon a day with the water changes. Im doing this so I don't shock them. I also fear that the salt may possibly be the reason for the flashing, but I have no clue.

I feed them Omega One super color food, Omega One bloodworms, and frozen brine shrimp.

I feed them three times a day, a little at a time. Oh and not all the foods at once obviously.


Now that you know my situation, my fish, and amount of fish, what I do to the tank and etc. what on earth could be wrong?

What could cause so many of them to "flash" and now so frequently, they seem to do it more after water changes. Could it be the salt? or the stress of the water change? I had a theory for about five seconds that maybe they were trying to get food out of the gravel, but I tossed that one out the window quick. Maybe the high ammonia levels? Or does it HAVE to be bacteria? and could this bacteria be caused from poo? or old food they may miss? The tank is only a week old. Please help.

Oh and besides the ammonia levels everything else is perfect.
 
Could you post the actual test results for ammonia, nitrite, nitrate and pH please? :)
Do you use a dechloronator to remove chlorine and chloramine from the tap water?

First of all, I recommend you reduce the amount you feed the fish to once every other day and remove any leftovers after about 3 minutes :) They won't starve (despite the looks they might give you) and it'll help keep the ammonia levels down a bit.

The irritation could be anything from poor water quality, to parasites, but in this case, I reckon it'll be poor water quality. You're already doing everything you can do for that, really.

I strongly advise you stop using the salt, as catfish like plecs are intolerant.

Bottled "cycling aids" don't really do much IME. Bacteria need oxygenated water and nutrients to survive - they cannot survive in a bottle for any period of time . . . certainly not the time it would take for the shop to actually sell the bottle.
 
I will get those results to you soon, I need to go get some ammonia testing strips. I took my water into the petstore to be tested and she didn't tell me exactly how high the ammonia was. and I was lied to, I was told that the 5 in 1 testing strips tested for ammonia when they don't so now I have to head back to the store and get some strictly ammonia testers.

And I am so upset about the bacteria supplements! What a waste. Sigh, well is it best to get water from an established tank then? I'm assuming so.

Thank you for your help!

I don't think I'll be adding any more salt to my tank from now on, I don't want to hurt my pleco!
 
Don't get the strips - they're absolutely rubbish (not to put too fine a point on it, lol). Get a liquid based test such as API (if you can get it)

Water from an established tank won't do much . . . see if you can get some media from a mature/established filter :) If not ask about Bio Spira (?) They're a form of live bacteria that are kept in the freezer in some pet shops and they basically do the same thing as mature media.
 
ok i have my results ph is around 6.8 and ammonia is around 0.5-0.7



oh and nitrite/nitrate are 0 or so close it barely made any color

they didnt have the refrigetated bacteria.

but i was very worried about the level being so close to 1.0 that i got a white carbom filter for a 20 gallon to make a slight adjustment.
 
Carbon won't have much of an affect on toxin levels - it's mainly fpr the removal of meds, tanins etc.

All you can really do is carry out daily partial water changes of around 15% with dechloronated water and hope they pull through.
 
so thats why my fishless cycle wasnt so disastrous! I forgot I put that frozen bacteria stuff in!

Are you supposed to leave them in forever? til they just disappear? mine kinda shrivelled a lot and when I cleaned my filter, I chucked them out.. since then my ammonia has been a little unstable.. slight fluctuations.

lastly, what is flashing?



I hope your fish are ok :)
 
Flashing is when the fish rub themselves on the gravel and decor of the tank. It happens so fast that it is like a flash of light and it's over in the blink of an eye. If it happens repeatedly, it could indicate parasites or water quality issues.
 
Alright I will continue to do that, They seem to be doing alright but I know they are not happy. One of my guppies had babbies last night, I don't know how many since the danios are crazy hunting them. I am feeding only once a day now and doing partial water changes, I have ordered a Rena XP2 filter and it will be here soon hopefully.

All I can do from here is hope that they survive and live happy live for the rest of their lives.

Thank you so much for your help!
 
A mature tank shouldn't depend on Bactinettes or Bio-Spira - they're just a colony booster. They'll give the best results if the filter bacteria have been damaged, but not completely wiped out. Sounds like the Bactinettes provided the majority of your filter bacteria.

You could always get some more if it help stabilise the colony, but daily partial water changes of around 15% will help keep ammonia at bay until the filter catches up to the bio-load :)

What are the inhabitants?
