[MENTION=1034]BruceP[/MENTION] Wellwehave a 38 Gallon tank. And we just had a couple
of gourami's and a pleco. They all died last week. We went to the
Sugar Bowl in New Orleans. We left on Sunday evening, and came back
Tues. evening. They were feed Sunday night before we left. Before that
I feed them every evening. When we came home Weds they were all 3
floating.
We have no clue what happened. Water temp was fine 72degrees.
We checked the water. The ammonia, nitrate's all were fine. The tank
has been up for years so it is an established tank.
So we tore it completely down last night and are going to start from
scratch today. We are going to have a cichlid tank now.
Im sorry, all my expertise is in goldies so I cant be much help. Sounds like it may have been a PH crash and only coincidental to you being away. If you add a little baking soda to the water when you do water changes it helps stabilize the ph and raises the GH which also helps. I don't know where you want your ph for cichlids but you do want it stable, I'm sure.
I have african cichlids, but only have two left.... and two plecos. They are easy to maintain because they like hard water so you just need to make sure you have the established bacteria. My suggestion is to just get one fish at a time, one ever 2 weeks when starting your tank. I always get over zelous and get like 5 fish a trip..... and end up with nitrate & nitrite issues! So I am 1/3 water changing everyday for a month!!! I would think I would learn my lesson......
