For all those who would like to raise/keep/breed fish or already do, I have some helpful tips on how to keep your tank healthy. Firstly, you want to prevent disease in the first place. So, I reccomend a quarantine tank. All it needs to be is a small, five or ten gallon aquarium with a filter, heater, and substrate, this is for keeping tropical fish, and you're set. When you bring in new fish. Leave them in the quarintine tank for the first few days or weeks if they will be breeders. Feed them twice daily at least, in very small amounts so as not to overfeed. Watch the fish carefully for signs of sickness: clamped find, raised scales, fungal growth, trouble swimming, little or no interest in eating, etc. If the need arises, you may need to drop in dissolvable fungus prevention tabs, or liquid ones. Clean the tank when new fish come in, replacing substrate if possible. If housing fry or very small fish, keep them in a breeder box. If fish show deformities, do not use for breeding. If you choose to cull, simply sever the fishes head, kill them with scissors, or smash them in a sock or wrapped paper towel with a hammer. I do not cull my fish unless in pain, when I use some plant snappers to decapitate or crush their brain cases. Once fish are introduced to the main tank, pond, etc., watch for any signs of stress, aggressiveness, or sickliness. Now it's time to plan ahead. What should you have handy if you're fish become diseased or infected? Here are some items to have handy: Methalyne blue Anti fungul tabs Aquarium salt Very good. If your tank becomes infected, you now have the stuff you need. What about feeding? I feed my breeders and hobby fish krill, bloodworms, tubifex worms, brine shrimp, mealworms, crickets, dead fry, and full freeze dried meals, some with vegetation. I also feed my fry and sometimes adult fish hard boiled egg yolk, thawed or fresh peas, tiny carrot or lettuce slices, and extremely finely sliced apple or pear as supplements. Breeding: If you are going to proceed to breed fish, I am assuming live bearers right now, you need to be ready and equipped. Here are things you will need: Breeder box/seperate baby tank Hard boiled egg yolk for fry and gravid fish Plenty of space for breeding fish A good balance of male to female fish Places for fry to hide when older A filter A heater Safety from larger fish for fry, they will be eaten! What kind of fish should I consider? This depends. I highly suggest a freshwater or brackish tank, as saltwater fish and animals are often taken from the wild, destroying reefs and depleting nature's supply of wild animals. For freshwater community tanks: Guppies Tetras Mosquito fish Cory cats Upside down catfish Plecos, or sucker cats Zebra danios Goldfish (they get over two ft, not meant for a tiny bowl) Killifish Koi (big tank or pond) Rosy red minnows (mostly as feeder fish) These following fish are meant for brackish water and will usually only live half their lifespan if kept in freshwater but breed very well; Mollies Swordtails Platys Brackish tank: Mollies Swordtails Pipefish Platys Mosquito fish Guppies Some catfish Oscars I don't have much experience with brackish tanks/ponds, so I'd love any suggestions for fish to add onto this list. Freshwater Cichlid Tank: Almost any Cichlid that fits in the particular category, such as African Cichlid aquarium WARNING: I DO NOT SUPPORT THE COLORING OF FISH OF ANY KIND. IT IS EXTREMELY CRUEL. FISH ARE INHUMANELY DYED WITH VERY HIGH DEATH RATES FOR OUR ENJOYMENT. THEY THEN ONLY LIVE HALF OF THEIR UNDYED COUTERPARTS' LIFESPAN. PLEASE DO NOT SUPPORT THIS. DO NOT BUY DYED FISH! IF YOU CAN, SEND A LETTER TO PETSHOPS THAT SELL DYED FISH AND TELL THEM THAT YOU WILL NOT BUY THEIR FISH. Thank you, I hope this thread helps everyone, from newbies to pros. Please ask if you have any questions or comments or are interested in possibly getting fish from our breeding lines.
