Hello! I posted a couple of days ago how I had a 30 gallon tank with five tiger barbs + 1 mystery snail. I am considering taking the Tiger barbs and putting in 1-2 fancy goldfish. I had a couple of questions specific to goldfish before I make any decisions.
- How many goldfish could live happy in 30 gallons?
- I have a substrate of 20 lbs sand and 5 lbs gravel (give or take a bit from time). Do you think they could come on gravel? And if yes, could I top it off with another form of substrate to cap it off and make it doable?
- is there a recommended species of goldfish for 30G? (Oranda, telescope, ranchu, lion head, etc.)
- Other than water quality being important , are there any things that are very important to now about goldfish?
- When switching from tiger barbs to goldfish, other then temperature what else would I need to change? Would I need to re-cycle?
