I have a 160L (I think around 55g?) with sand substrate, rocks, caves, driftwood, plants, couple air stones filtered by Aquis1250.
4x sterbai corys
2x kribs
2x gold angels (had 3) - just got them in the last few weeks
about a dozen male guppies including some juveniles
Temp sits around 27C with pH about 7.4-7.6 (same as local tap water). Parameters today are ammonia 0 nitrites 0 nitrates - about 30? colour darker than 20 but not as 'red' as 40 (aqua one strips test).
Yesterday I woke to find a dead angel it had a distended tummy (especially on one side) with one side looking like it had an internal bleed. I asked the previous owner if they'd had anything happen like that before but haven't heard back yet. Can't seem to find any exact description via google... We were away for a couple of days before that so I hadn't noticed any unusual behaviour.
Then today I noticed my krib that spends all it's time hiding... just sitting in the middle of the water column. She has a cloudy eye on one side. Googling suggests an injury which is possible from a fight with the other krib or maybe the angels. Or I have seen the kribs squeezing down the side of my new snail trap which might have some sharp bits poking out from making the holes... but she's definitely not acting her usual self.
So far everyone else is fine...
But... a few weeks ago I had a cory die-off - 4 cories out of 6 died - and I still haven't figured out the reason.
Could this be related? Could there be some nasty underlying thing going on in my tank?
I've only had the tank set up for a few months, although it was second hand and came with the substrate... if I was getting ammonia spikes, wouldn't my parameters at least show nitrites?
Hope I've given enough info without info overload LOL...! Still so much to learn in this game and I'm keen to know if these things are just part and parcel, or if there's something I need to improve.
PS re the angel it could have over-eaten, as they're very greedy - and polish off the food I put down for the cory's as soon as they've finished their own!
