in the future will will be buying a 55gal tank for african cichlids. Ive read alot of articles on it and still i have unaswered questions.
1. Should i go with sand or gravel, will the sand affect my hang on filter?
2. would one hang on power filter be enough water movement for my tank?
3. would the catfish i get be affected by the sand?
I have got a list of what i might put in it
2- angelfish=12 inch
3 eletric yellow= 15
3 electric blue = 15
What should my clean up crew be?
could i add a discus? do you like the setup? suggestions for what fish to have in it?
For your tank if you go w/ the africans the discus and angels will not be compatable, they require different water
pH/hardness and food.
Sand and c rushed coral is great for africans (it raises the ph and hardness), if you go w/ discus find a substrate that will do the opposite or be neutral.
A biowheel and a canister on opp sides is what I put on my cichild tanks.
Catfish are fine w/ sand. Just be careful of the pleco/fish you choose some need low ph, some are more compatable w/ africans than others.
For africans they are their own clean up crew, they eat algae off the rocks and back grass (they are veggie eaters).
For the discus and angel any type of pleco suited for your size tank that eats algae is great.
If you do a 55 african you can put in 15 total fish (inches per gallon rule doesn't apply w/ africans, you need to overstock for aggression)
The electric yellow are peaceful, the blues are aggressive I wouldn't mix them..
the cookie cutter info is great above on Mathas post.
Discus really aren't for a begainer, they have to have prestine water conditions, warmer water than most fish.
