moldyform Posted January 3, 2012 Share Posted January 3, 2012 Gdayive got a community tank with tetra, guppies, silver sharks and bristle nose. The fish are all starting to die off. Ive checked the water quality and it all seems fine and is as followsph:7.5ammonia:0GH:160nitrates:0temp:28The fish are in top notch condition then with in a day they start to loose their balance and go in rapid circles. Also a few tetras became bloated and then die. Once they die the majority look healthy and perfect condition. So far ive had die about 30 guppies, silver shark, 30 neons, guramie, and some rummy nose tetra.Ive gone back over teh changes ive made in the last month or so but cant see anything that would trigger this. Some things ive done was Start up my second canister filter after a break.added a stack of plantsadded a small amount of pond weed form out door gold fish pond.added T5 lighting (some blue tubes as they were from a marine tank)Any suggestions? Ive done a 65% water change but still had a few guppies doing upside down laps with reverse twists this morning.Cheers Link to comment Share on other sites More sharing options...
E4G13M4N Posted January 3, 2012 Share Posted January 3, 2012 A lot of factors may come into this mix but things to start with7.5ph is too high for neons, yes some may survive but its way out of their parameters they prefer soft water 5-7ph although other tetras will do fine at this phtemp is also too high for neons and guppys they both prefer temperate temps of 18 - 24 a too high temp with guppys can bring on camallaris (SP)These are just the basicalso what is theKH and nitrites they may also play a part in the problemRapid circles can also mean some form of toxin in the water, which may be affecting the fish that are under stress, can also be an indication of worms Link to comment Share on other sites More sharing options...
Joel Posted January 3, 2012 Share Posted January 3, 2012 Start up my second canister filter after a break.When you say after a break, how long do you mean?. Was the filter cleaned before you put it back in the tank?It could be that there were some nasties within the filter media which would have been pumped around the tank when you started it back up again.Are you sure of your readings? Fish dying rapidly is usually due to ammonia spikes or even nitrite spikes in my experience.I assume you tank is well aerated. You have lost quite a few fish. Not sure of your tank size but if it is small and you have heaps of fish, combined with high temperature, oxygen gets stripped from the tank pretty fast.Also, how long has the tank been setup for?Hope it comes good for you.Cheers Link to comment Share on other sites More sharing options...
moldyform Posted January 3, 2012 Author Share Posted January 3, 2012 Thanks for the replies guys. Ive had the tank set up for about 3 years as a community tank. The silver shark that dies was about 4 years old.Ok so ill drop the temp down to 25 and reduce the ph to 7. How will other fish tolerate these conditions?Yes im farirly certiain about the water quality. Tested in number of times and double checked at the fish shop. However i havent checked teh nitrite yet I dont think. The guppies seem to be breeding quiet well still tho.The tank is 6x2x2. Im using a blower to airate the water.The canister filter was leaking through the bung on top so i siliconed it up. It was not reconnected for about 3 weeks after i sealed it. I cleaned it out thougherly after i disconnected it but didnt wash it out before reconnecting it back to the tank.So im wondering what i should do from here? Do more water changes and bring ph and temp down? Link to comment Share on other sites More sharing options...
Ducksta Posted January 3, 2012 Share Posted January 3, 2012 Had any pest control around the house or excessive aerosol use round the room the tank is in lately? Link to comment Share on other sites More sharing options...
moldyform Posted January 3, 2012 Author Share Posted January 3, 2012 Nope, strictly no sprays in the fish room. Link to comment Share on other sites More sharing options...
Josh Posted January 3, 2012 Share Posted January 3, 2012 Do you have any fish on the pond? Is it possible you introduce a disease/contaminate from the pond to your tank? Link to comment Share on other sites More sharing options...

Jarrods Posted January 3, 2012 Share Posted January 3, 2012 I am pretty sure in a properly cycled tank you won't get a 0 nitrate reading. You would get a 0 nitrite reading though. What where you using to test nitrates? Link to comment Share on other sites More sharing options...
E4G13M4N Posted January 3, 2012 Share Posted January 3, 2012 the PH is fine for the guppies, but not for the neons,0 nitrates is possible in a well planted tank..As per Ducksta if not a spray recently, any hand creams been used lately as toxins can be introduced in many ways .

LithoMan Posted January 3, 2012 Share Posted January 3, 2012 cleaned your filter lately ? i did that once and a water change same time killed a heap of fish .all the good bacteria gone Link to comment Share on other sites More sharing options...
moldyform Posted January 3, 2012 Author Share Posted January 3, 2012 Josh, yep ive got a few gold fish in the pond. I just grabbed a hand full of the pond weed out of it. Suppose that is a possibility.Im just using ANI test kit for the nitrates. I did another test last night and it is pretty much 0 now.Litho, i have 2 aqua one 1200 filters. one has been running continuously for about 3 months with out a clean so it should be running pretty ok. The repaired filter was a fresh start, complete clean out and sat for a about 3 weeks before i reconnected it.Also what the best way to get the temperature down these days? I have the heater set on 23 and it is staying on a constant 27. Link to comment Share on other sites More sharing options...
moldyform Posted January 5, 2012 Author Share Posted January 5, 2012 Ive still got a reading of 5 for nitrates. What could be causing that?Had a cherry barb die yesty and it was bloated to the max before it died and by the morning when i went to get it out it was covered in a white hair fungus!!! Really bazzar! Link to comment Share on other sites More sharing options...
Aquaholic Posted January 5, 2012 Share Posted January 5, 2012 I think it was a disease from the pond. A nitrate reading of 5 - 10 is normal. Link to comment Share on other sites More sharing options...
Skippy Posted January 5, 2012 Share Posted January 5, 2012 Ive still got a reading of 5 for nitrates. What could be causing that?Had a cherry barb die yesty and it was bloated to the max before it died and by the morning when i went to get it out it was covered in a white hair fungus!!! Really bazzar!Nitrate is the end result of the nitrogen cycle. Correct me if I missed something but you had nitrates readings of 0 and now it is 5, unless you are running a well planted tank, it sounds to me like your tank has gone through a new cycle. Shame you didn't measure nitrites along the way. Link to comment Share on other sites More sharing options...
moldyform Posted January 5, 2012 Author Share Posted January 5, 2012 Yeah might be what happened when I started up the second filter skippy?Is there any way to detox the tank if it is a disease from the pond? Link to comment Share on other sites More sharing options...
moldyform Posted January 25, 2012 Author Share Posted January 25, 2012 Its all started to finally settle down. The surviving fish must be top notch quality to have survived the epidemic.However, Im not sure if its related or not but im now starting to get large amounts of green hair algae. Will any fish clean this up? Or is there some treatment other then pulling the individual strands that are rappidly taking over? Link to comment Share on other sites More sharing options...
