Overstocked?

Recommended Posts

Well I went to the LFS for some rocks, but ended out coming out with 2 Hongi and 1 b.electric (they had no rocks - . -)

So now I have:

2 x yellow.e

2 x blue.e

2 x Hongi

2 x mainago

4 x cabro

is this too much for a 36x14x18? If you apply the 1" to a gallon rule, this is getting too stocked or am I ok?

I seem to recall reading that the 1" per gallon rule isn't very useful for malawi cichlids, where a bit of overcrowding is "recommended" to reduce aggression (or at least ensure that it is evenly distributed).

The rule I've been going with is 1" per 10 sq. inch of surface area. This implies that you can only have as many fish as the water's oxygenation supports.

I'd estimate maximum body lengths (ie heads and caudal fins/tails NOT included) for your fish as follows:

Labidochromis caeruleus (electric yellow) = 4"

Labidochromis sp. "Hongi Island" (hongi) = 4"

Melanochromis cyaneorhabdos (maingaino) = 4"

Pseudotropheus crabro (bumblebee/hornet) = 6"

Sciaenochromis fryeri (electric blue) = 8"

Given your tank dimensions, and assuming the height of the tank is 18", your tank's surface area works out to 36x14 = 50.4".

Your fish total (when the fish are fully grown) works out to

2x4 + 2x8 + 2x4 + 2x4 + 4x6 = 64

According to the rule, this is too much!

Cheers, Paul.

For my own tank:

Labidochromis caeruleus (electric yellow) = 9x4" = 36

Iodotropheus sprengerae (rusty) = 4x4" = 16

Melanochromis cyaneorhabdos (maingaino) = 5x4" = 20

Pseudotropheus socolofi (pindani) = 6x6" = 36

Total = 108

My tank = 48"x15" = 720 sq. in. => 72" worth of fish (normally).

So,...

I also apply the "add 50% for Malawis" rule!! cool.gif

720x1.5 = 1080 ie my tank is just right! thumb.gif

(I also have three airstones bubbling away in the tank, together with a near-surface-mounted internal powerfilter to supplement the external canister.)

Cheers

I think the tank is too small for crabo. Chance of problems when they grow up. A male electric blue could also eventually cause problems. Malawi cichlids are polygamous mouthbrooders, they don't form pairs. 1M/3F is alot safer than 2. Manganos may only get to 4 in. but they can be a bit aggessive as well.
