I am new here and I have a 75 gallon tank with:
1-Leopard bushfish
1-Gold-red Severum
1- Leopirnus Arcus (lipstick Leporinus)
1- Starry night eel
1- EBJD
1- butis butis (crazy fish)
3- Geophagus Abalios
1- L600
1- L400
1- L128
1- L190(might be getting rid of he is messy

)
Now I know that is alot but I am running 2 110 Aquaclears and water change every week when home from school but when im not home brother feeds and does water chages every 2 weeks.
Well when i was at cichlid world the other day the lady said my tank was understocked!! which I thought the opposite, but hey shes been working with fish much longer then i have. Also, when i have went to Fantastic Fins (FF) they have told me that i could put peacocks or other haps with what i have because they are not that aggresive i guess.
Finally, the reason I ask if i can mix is because I have up at school a pair of Lake victorian obliquidens (red fin i believe)(they are in a friends 55) that I need to bring home this summer and wanted to see if i could put them in my 75 with what i have?
Ideas? or suggestions? or any comments help
