Not to disagree, but that's news to me. Been raising discus for close to 10 years, know close to 150 other breeders/hobbyists and have participated/assembled numerous shows in Florida for discus breeders over the last 5 years and I know for a fact that no one I've met changes the water that much for their discus. Now, we do cycle the water at the breeding facility at least twice a day through specialized water filters to help remove the levels of nitrates and ammonia that are damaging, but have NEVER done 100% water changes *daily*, nor have I heard of it.Pufferpunk wrote:Your good bacteria lives on surfaces, not in the water column. I do 90% weekly on many of my tanks--discus breeders do 100% daily on theirs.
I guess this is part of that "psychological trick" people like to push out there to make people think that discus are hard to raise, I find them way easier than my collection of puffers (fw and bw - 72 specimen) to keep.
In my humble opinion, people excessively change their water because of their lack of understanding how to efficiently monitor their tanks stability, which creates frustration because people can feel burdened by their tank responsibilities (having to work a second job almost just to keep things running the way some suggest). My private puffer (fish) room at my home has 3200 gallons of water, depending on the tank and species of puffers, I do water changes every other week. Obviously some puffers require more, based on their dietary needs and how feedings can effect water stability.
Now - after reading around here - I know what most people on this forum would say, "Well, then your fish are not going to live as long and be as healthy as they could be...", of course that'd be an interesting statement considering I have 3 GSP's that I bought from a Fish farm 10 years ago and they were adolescents when I got them (I'd say 2 years old already) and are still thriving, I lost my first GSP last year (had him 9 years, was 5" when I got him). There are more dangers and mistakes that people make with these fish than missing water changes... like buying them to begin with thinking they are like goldfish and are easy to care for - which is extremely stupid. People should read about them, and if they buy them and can't take proper care of them should take them back to the store where they'll have a fighting chance and possibly fall into the hands of someone who can give them the necessary care.
Also, since we're on the subject of tank size. GSP's can EASILY live in 20 gallon long tanks by themselves, I've put 3 of them in 55 gallon breeders numerous times and never had any issues, and if it weren't for the fact that I needed their tanks for breeding pairs of puffers, would still have them today (gave them to friends or family after they fell for their spellbinding little personalities and those incredible eyes), all of which are still alive and healthy today.
I've found that (almost excessively) creating hiding spaces for these fish reduce loads of stress and prevents them from nipping their tank mates, my tanks look VERY crowded (90% of my tanks are planted with tons of driftwood and caves for them to hide, also are placed in custom wood cabinetry/panelling) but my fish outlive their life expectancy. There's a lot of good info on this website about keeping them, I can see how it'd be a great starting point, but I'm definitely on the side of slowing down the importation of these fish altogether - my apologies about the passive-rant.
Lastly, to add my comments on these puffers having seizures... never heard of such, never even seen any species of puffer (only keep fw and bw species) go into seizures.
Well, that's my .75c for what its' worth - will try to be on this site more to help, handled tons of fish ailments and can indentify 90% of the diseases (15) commonly effecting fish.
