Feeding a lot of microworms are being blamed for many fry not developing their ventral fins.
Here was my list when I began a breeding set up. I started with enough for 2 spawns -
- Spawn tank - you don't need to go larger for it.. anywhere from 3 gallons to 10 works good as you will want the water down to 3-5 inches to help the male grab the eggs easier. You can have the tank full of water, but the larger the tank, the harder it will be for the male to keep up with falling eggs and fry. I purchased a 37L (10g) and fill it up to about 3 gallons.
- Two grow out tanks, each 113L + (30g) to make sure to give them plenty of room to swim/grow, and to avoid a quicker build up of waste and stunt hormones.
- A heater that will go up to 29*C (84/85*F) 1 for the breeding tank, 1 for each grow out tank.
- Sponge filters for each tank.
- Lots of live plants to help keep the water cleaner.
- Glass canopy for each tank to help keep the humidity in the tank which is very important.
- Lots of airline tubing - for the pump(s) for the sponge filters and BBS hatchery, and to suction out waste from fry tank.
- Turkey baster
- Thermometer for each tank
- Lots of IAL (for the tannin, along with using a part of a leaf + bubble wrap as a nest anchor)
- A few buckets as you will be doing daily water changes
- A 100+ separation containers - people use beanie containters or large deli cups (32oz+) and large jars. 17 isn't enough unless you plan on culling most of your spawn.
- A way to heat all of those containers (I use a very large and shallow plastic storage containers and 100w heaters in each one.. place some water in the bin with a heater and place the containers in the water to help keep them all warm)
- Multiple fry food - I have banana worms to start them out on (infusoria is only for the first couple of days), then microworms and then BBS.. after a while I have a couple different fry specific food I will use to help transfer them from live food to processed foods like pellets.
I know I have a lot more.. but can't really think right now, a little tired.. but you get the idea.
BBS may be a bit expensive, but a big can of it (if kept in the fridge) can last well over a year if you are only doing one spawn at a time.
Here is a list
from one of the stickies at the top of this section (under Breeding information
). It may help you get an idea of what is needed.
