Does anyone here noticed if there is an effect of the day length on the size of tilapia's gonads?

Comment by Randall Wimbish on April 9, 2014 at 6:29pm

Pablo. It is just a food grade dark color that will not be toxic and will wash off when you put the fish back in the aquarium. Thinking outside the box you could possibily use the juice from a can of beets or maybe squeeze a blueberry or blackberry????

ah ok.. thanks Randall... i thought there was something specific.

Comment by Randall Wimbish on April 8, 2014 at 6:36pm

In the USA we can go to the grocery store and buy food coloring to add to cookies, cakes, tortillas, Easter eggs and things. We find it in the same section as the spices.

Thanks Randall... what do you mean by red food coloring?

Comment by Randall Wimbish on April 7, 2014 at 5:24pm

You can sex them by putting some red food coloring on their bottoms. males have two openings and females have three. You also need to put some caves in the aquarium for the ones being chased to back into when they get tired. Most people cut 4" pvc into short caves and zip tie them together like a little fish hotel. Others use clay flower pots I think.

Identifing tilapia for reproduction

Hi Everyone,

I have 15 tilapias and just separated 3 to a new aquarium with the purpose of reproduction.


I placed here what i thought could be a male and 2 females, however, I have been analyzing their behavior and i am a bit confused, so i took few videos in order to place the question in few groups.

If anybody can help me i will appreciate.


Details of system:


Width: 1 foot

Height: 16 inches

Length: 30 inches

Volume: 94 Liters = 25 US gallons



Temp: 27 Celsius = 80 Fahrenheit


You will see 3 tilapias:

1. Largest one

2. Sort of like singular colour, with fins black/metallic

and Pectoral fins redish.

3. It has more black lines along the body. Smaller of the 3.


#2 seems pretty aggressive and chasing the other two.. They have actually jumped out of the aquarium.


there is mouth fight, especially between #1 and #2,


#3 seems to be chased more than any, though #2 chased #1 even though is bigger.


I am starting to think that 1 and 2 could be males, so i am looking for some insights from all of you.

Thanks in advance.

Okay everyone. my male is just very lazy he did not dig a hole/ pit  but instead let them in his pvc and one of my females now has eggs in her mouth.

 Hi Randall,

  $14.00 a lb  for 1-4 inch fingerlings is very reasonable. I bought some of mine for almost $2.00 a piece and it is cost prohibitive for what I plan to do which is raise them for food for us and cook or dehydrate them for chicken feed.  




Comment by Shelia Hoyt on December 29, 2013 at 8:26pm

No, Bob,

  I do not have a radio flow filter. I have an in ground koi pond 300 gallon  for my sump that pumps into my fish tank and then directly into my grow beds so they would be pumped into the gravel if any had been hatched.

  I did not put any PVC or hiding places in my tanks past summer. Also I keep the water between 68-74 with the help of solar heat and wood heat and a heat exchanger. It would be very difficult to keep the water in the upper 70's and 80's through the winter and I do not want to burn that much wood... So I have a large aquarium in my house for the breeders. The first time I placed the first batch  in the tank  they bred with in a week...
