i also have another one. my fish getting some disease that i’m not ready for and me needing to go out and buy stuff but having no money and my parents won’t chip in (not even a loan) because they don’t like my fish.
The odds of that actually happening, especially to someone relatively young and new to the hobby, are frighteningly high!
Been there, done that and got the T-shirt.
(Actually, I had a few thousand T-shirts made and they all sold out very quickly
).
I'd suggest saving your pennies and slowly building up a supply of Emergency Items. These would include spare heaters, airpump and stones and maybe even a spare filter and tank.*
(*A spare tank is ALWAYS handy, but then we have a tendency to fill it and stock it and then need to find another
really 'spare' tank
I use my 'spare' tank to keep all of my Emergency Items in). Only some of these will be used on a regular basis anyway, but I always have these to hand;
Algae remover.
Anti-bacteria medication.
Anti-fungus medication.
Anti-ich medication.
Aquarium Salt...used on a regular basis.
General Cure medication.
Live bacteria.
Plant food...used on a regular basis.
Water Conditioner...used on a regular basis.
Obviously, proper care and maintenance of your tank will greatly reduce the need for any of the medications, but I strongly believe that it's always better to have something and not need it, to needing something and not having it! (Blame my Scouting and 'Be Prepared' ethos). True, meds are not cheap, but they have a long shelf-life, especially if un-opened and these should be used with utmost care, only after other solutions to whatever issue you're dealing with have been explored.
