We have a 40gal Aquarium with the following healthy fish:
Pair o' guppies
2 sunburst wag platies
2-3 velvet red swords
5-6 tetras (strawberry)
2 scavanging catfish (small)
Been up and running since 1/3/07 - slowly adding fish.
I previously lost two plecos and a catfish in relatively short order. Chaulked it up to perhaps not enough food for scavengers, so left it alone with the two small scavengers (catfish).
There's plenty of visible algae now :)
Well today, I added one pleco (relatively small about 1.5" long). I just spotted him upside down on the bottom still breating.
I am scratching my head trying to figure out what might have gone wrong.
I thought plecos were practically indestructable.
I do water changes every 2-3wks and my test results, look pretty good.
Here's the latest after doing an H20 (40% change) a couple of days ago.
I add FritzGuard, Fritz deChlor & salt per my LFS recommendation.
Alk / Buff capacity 300+ (related to PH below?)
PH 8.0 to 8.4 ( a little high, but hard on the pleco?)
I think (perhaps I should do another H20 change ASAP?)
What about the pH, I've heard conflicting info there.??
