    So sorry for your loss.  That's really frustrating with a big purchase like that. 

    Without knowing more, I would agree with @Colu and @GameCzar.  The owner of a highly respected/beloved LFS in my area (has been featured in an AC tour video) calls sudden pH changes a "silent killer" and sends every new customer home with a drip acclimating cup and instructions to very slowly introduce fish and not to add the new fish to your tank until the pH is the same in your tank and the water your new fish are in. 

    hope your survivors do ok.

    Yeah so from a biological perspective fish use the pH of the water to adjust their sodium ion channels. When a fish is suddenly introduced to much higher pH than they are accustomed to as a response the membrane over the fish's gills thicken making it harder to breath and to regulate their sodium channels. Sodium is used in everything in a fish's life from osmotic pressure to synaptic firing of nerve cells. 

     

    Sorry for your losses though! It is really not a great feeling losing your whole group😢

    First, thank you all for taking the time to reply.

    Reading Aquarium Science ( 4. Water Parameters Index (aquariumscience.org )

    There are many myths about the water in which aquarium fish live. Some of these myths are:

     

    • Rapid changes (in seconds) in water parameters (pH, hardness and/or temperature) can damage or kill freshwater fish.

    And...

    The water fish swim in is very important, obviously. But it is not nearly as important as people give it credit for. The chemistry of the water, the pH, the hardness and the salts contained in the water, are just not very important to the well-being of the fish. Most tap water between a pH of 6.5 and 8.5 is fine for all fish. Add conditioner if the water had chlorine in it and you’re good to go.

    And...

    The hobbyist should not “chase” pH with chemicals. It is not dangerous, contrary to popular myth. But chasing pH will just frustrate the hobbyist. The pH in an aquarium changes all the time quite unpredictably. A swing as large as 6.5 pH to 8.0 pH in ten hours is quite common in aquariums. Also the test kits for pH are simply not very accurate. Indeed the electronic meters for testing pH are sometimes more inaccurate that the test kits as they need careful storage and calibration.

    And...

    4.4.1. Aquarium pH is Not Important (aquariumscience.org)

     

    From this guy articles it is clear that PH does not mean much but your answers somewhat contradict it. Also, the shop owner told me that all he does when he introduce new fish to his tanks is floating them for 15min. and then into the water. I usually float them and slowly mix the water in the bag with water from the tank.

    So assuming that the website is incorrect then the question should be asked; Is a slow change (say over 40min.) of water in the fish bag is enough time for it to adjust to new water parameters? Also, per the shop, they don't do it and their fish are well and alive, also, on a separate thread (can't remember which) many said that all they do is "throwing the fish into the tank" and that this is what is done to the fish during their journey to us...and all/most of these fish are well and alive.

    So who is right and who is wrong? Or, both are right and wrong at the same time? I know, many question marks and very confused. 

    The shop tested my water and were happy with it and gave me a full credit, will have more fish in a week or two once I am sure that there is nothing funny happening to the water.

    I have read a few things on old tank syndrome. I have not read much as I have not experienced this but it’s something you may wish to look into. Fish in tank are adapted to things that negatively impact new comers is the just of it. 

    Thanks. Will do some reading. However, the tank that the Fork Tails were moved to and the Corys were introduced was set up only 2-3 weeks ago so all the 'old fish' are inside for not longer than 2-3 weeks, therefore I don't think that old tank syndrome is the reason. As for the other tank I have changed water one week earlier.

    How did you acclimate the fish to the new tank? How were they acting post introducing them?

    Floating them for 30min. The shop has the same water as me as they are only 5 miles away.

    Over the weekend we bought new fish.

    17 Celestial Pearl Danio (Galaxy Rasbora).

    6 Indian Glass fish

    3 Adolpho Corydoras

    6 Agasizi Corydoras

    To date all danios, Adolpho and X1 Agasizi are dead. The strange thing is that the Danios were in a tank that few minutes earlier had 15 Fork Tail Blue Eye fish that were moved to a larger tank with other fish, I didn't change the water and left all shrimps for company. The tank that the Fork tails were moved to is the one that the Corys were introduced to, this tank had 3 Adolpho that were moved into it 2 weeks earlier. The Glass fish are in another container and seems to be ok. All original fish and all shrimps are doing well, only the new comers died. Went today to the shop and all the remaining fish there are doing well (other than the Danios as I bought them all). 

    I have tested the water and Ammonia and Nitrite are '0', PH '8' and Nitrate '50' KH and GH were not tested, regardless I have changed water.

    Any ideas?

    Thanks

    Catching fish

    in General Discussion

    Posted

    How do you catch fish in a 2'2" high planted tank? I need to catch 6 Cories and 2 Celebes that outsmart me.

    I have built a special net by using an anti midgets net with an inserted metal wire to create a circle. This Celebes learned that this net causes fish to disappear and avoid it while the Cories are inside the plants.

    Thanks

    New Tank

    in General Discussion

    Posted

    The new 200ltr (~75gl) tank has arrived yesterday. Today I have set it up filled it just under 50% with fresh water and stuck an air stone inside. Tomorrow I plan to plant it, position the wood and fill it with water that will be taken out (~100ltr) from my other tank during the two weekly water change. Also, I plan to move X2 pre filter sponges and X2 sponge trays from the established tank to the new tank and start running the filter, the fish will be moved from the containers on Sunday.

    Is their something that I have missed or should have done differently?

    Thanks as always

    Thermometers: What The Heck!

    But the thermometer I use most often is my hand. If the water luke/cool it is low 70s F. If the water is lukewarm, it is middle 70s F, is the water is warmish it is about 80 and if the water is warm it is upper 80s.

    It is the same principal as my Stone Weather Centre, very accurate and 100% reliable:

    If the stone is wet ; It is raining.

    If the stone is dry; It is not raining.

    If the stone is white; It is icy or snowing.

    If the stone has gone; there is Hurricane.

    A quick question

    Why didn't the superglue work?

    I used gel superglue and for whatever reason it has never hardened/dry. My LFS does sale marine fish so I will check about the patty. I wanted to use a DIY glue but didn't feel comfortable about it.

    most aquariums are sealed with silicone.  now not all silicones are fish safe, but it is readily available.

    Yes, you are right, I didn't make myself clear. I thought about household silicon, I don't understand why clear silicon for home use can't be used for an aquarium but I don't want to take the risk.

    GE Silicone 1 is fish safe after it cures. 

    Thanks, already did. The LFS sells small tubes so will see them tomorrow.

    Thank you all for your time and advise!

    what type of heater do you guys recommend?

    in General Discussion

    Posted

    I try to keep the tank clean of wires, pipes etc. hence all my heaters are inside the filter, other than esthetics it also provide a better heat distribution. All heater are controlled by Inkbird controller that are set to 1.5C above my required temp that is set on the heater's thermostat. If you decide to have immerse heaters make sure to have covers on them to prevent injury to fish if are touched. In my quarantine tank I have some suckers who love to attach themselves to the heater and the cover helps.

    Other than that I think that Steph's is a good idea.

    A good shrimp problem

    Some months ago I have added 3 Amano and (I think) 5 Cherries, 1 Bumble Bee and 1 Green (that have changed into yellow) shrimps, now the tank is teaming with shrimps of all sizes, mainly very small and small to medium. There are many Cherries, 1 baby yellow and some that have the same pattern as the Amano (the Amano lady is 2" long, fat and very aggressive eater) so I am watching carefully before declaring them as Amano babies 🙂.

    I need to vacuum the sand but because of the fry I just change water, thinking that they will grow a bit and that will make the job easier but the shrimps don't stop breading.

    How can I vacuum the bottom without sucking them out? I have rejected the idea of a mash on the inlet or outlet of the siphon because it will also trap the rubbish. Any ideas?

    Thanks

    Compering the two photos...and I can't see many similarities.

    The rear end of the D.F Nymph photo as provided by @Guppysnail is different to the one that was originally attached, also, the rear legs angles are not the same as well the the pattern on the back.
