i thought it was normal then they would bend in half and with in hours be bloated on the surface.
i think the salt may have helped some because they have not bent in half, yet, and 2 seem less bloated, but there is no poo anywere to be found. thats not counting on the guppies not eating it. i'll see how it goes. i may go pick up some hornwert for added everything. i'll prazi as a last ditch effort. i use it on bigger fish and rays, but these small gars and other small gar i have never done it before and these are irreplaceable to me. i have a crazy thing with firsts and these are my first lng fry, my first gars i've caught and they are not something that, well, any lfs or vendor has now that tfd has gone under.
i wouldn't count on the guppies eating all the waste from the LNG, so if they are producing waste you should definitely see it. good that they are still hanging on though. definitely save the fish if they die so you can necropsy them and maybe see what the issue was...definitely DO NOT feed them to your other gars; if you think they had bloat or some other problem, the last thing you want to do is risk introducing the issue to your larger fishes (even if they are likely less susceptible...at this point we don't know what it is).
i wouldn't risk prazi...as Amy said, these little guys are likely too fragile for that, and i wouldn't try that with them unless you have absolutely no other options. i would try epsom salts before prazi personally, but for now just leave the system be and see if they can counter the issue on their own. good luck--
