LOL my stock list is cringe worthy(the tank looks empty because a majority of the loaches are already in their hole:
30+ clown loaches
3 red tail loach
1 Syno cat
4 plecos(gold nugget, blue phantom, vampire, albino sailfin)
2 redhook silver dollar
2 wide bar SD
2 narrow bar SD
5 tinfoil barbs
3 bala sharks
a pair of jewel fish
5 Central/South American Cichilds(texas, JD, GT, V. Syn, convict)
23 African Cichlids(1 red empress, 2 electric blue, 6 yellow labs, 2 deep water hap, 2 eye biter, 1 A. Chrysti, 1 blue dolphin, 1 taiwan reef, 3 OB peacock, 2 sunshine, 2 misc peacocks)
Since none of the fish are tank buster range(the loaches can be but all of them are of 2"-5" range), I go by water quality. With lots of portos and twice a week 40% water changes, nitrates are somewhere between 0 and 20 ppm. Even after 5 weeks of no water change(vacation) the nitrate rose just a tad above 40 ppm(fixed already)
No aggression with the exception that the 3 redtail loaches would fight each other sometimes.
Key to this is: the dithers are bigger and quicker than the cichlids...
Africans are milder varieties(no psychos like Kenyi), No possible CA/SA pairs....The only potential pair is the Jewel but they are just too small to do anything.
