I have a group of 18 month old Tropheus duboisi "Halembe/Maswa" in a 90 gallon tank, with Aragonite sand, some
Rocks and a few live plants. Eheim canister filter, two powerheads, Current USA LED lighting. They share the tank with my breeding colony of Neolamprologus similis. I have had the Trophs since they were about 1"; the largest are now just over 4".
Parameters:
Temp: 27C
Ammonia: 0
Nitrite: 0
Nitrate: 15 (did a water change as I like to keep it under 10)
pH: 8.7
Feed: NLS Cichlid 1x daily, NLS AlgaeMax 1x day, zucchini or other veg 3x week, spiralina brine shrimp 1x week (scraps, target fed to the similis but the Trophs always grab a couple, never had an issue)
My largest fish and my second largest fish were flirting pretty heavily the last two weeks or so. Today I noticed the second largest fish (presumably female thoug I haven't vented them) has changed her behaviour quite a bit. She is usually really outgoing and bossy, but now she is hanging out in some rocks and is very dark. Her yellow band has all but disappeared. She is even letting the smallest Trophs push her around. She is still eating, but not with the same gusto as I'm used to. She doesn't look bloated or distended and there hasn't been any change in food or feeding regimen. Her jaw doesn't look terribly distended, though it's kinda hard to tell.
What do you guys think? Sick or holding or...?
I'll post a couple pics once I figure out how to resize images lol
