So I'm trying to get the equipment and possibly the tank second hand so that I can spend more on the hardscape haha! Need to decide on the tank size but I can get FX4s and 6s for about £100-£120. I'd like 2 on there but I'll start with one to save cost. Also going for MD's LED lights from Amazon which will only be about £24-36 over all.
I know the rest of the cost is a lot though.
Hey! Can we get an update on how the tank plans are going please?
I like the sand you linked too, I'd go for it! Yes, setting up a tank is crazy expensive, but for a dream set up especially, for fish that you've wanted for a long time, it's worth it. You also clearly know the best ways to save some money, and you don't have time pressure forcing you to make decisions fast, so can take the time to hunt for great deals second hand!
About which of the tanks to choose - It's probably going to depend on what's available since you're going for second hand. I buy second hand tanks from gumtree too, brand new tanks are crazy expensive! And you can find some real bargains when people are closing down their tanks, especially a big tank that they want gone because they need the space.
Since you have space for, and want the 90, obviously hunt for that one - the bigger the better. But if you find say, a 90 in poor condition/very expensive, and a 75 of the brand/model you're after that's in great condition and a bargain, you can decide to go for that one instead. I'd focus on getting the tank first, since you can't do much with hardscape, substrate etc until you have a tank!
I don't know cichlids at all, so forgive me if this is a daft question! But the idea of the three female nics, and one possibly being brighter and leaving the other two more drab, while at the same time, perhaps it could work since they're gregarious in the wild - do you think it would be possible for you to try it out? Get the three, and perhaps it will work beautifully. But if it's not working for whatever reason, keep your favourite, and rehome the other two? Or is that you'd need to stock the other fish before introducing the cichlids due to territorial nature, so need to know the numbers first, and removing/restocking if you end up rehoming two would be a nightmare?
