hi my name is cris and i am new to this forum. my girlfriend and i have a hagen fluval 55 long aquarium kit, came with filter/heater etc. anyways, our tank has been set up for approx 4 months. we have recently purchased 2 german blue rams and 2 golden rams. our problem, is that 2 sundays ago, while doing a gravel vac, mysteriously one of our new gold rams got extremely stressed out. unfortunately, all it did for 24 hours was lie on the gravel sideways breathing extremely heavily. it died after about a day
and then this sunday, when doing a water change, the same thing happened to one of our blue rams. i must be doing something wrong, any suggestions or questions about how/what i am doing to gravel vac? i do approximately 20% water changes
